Exits shall be continuous from the point of entry into the exit to the exit discharge. Reason: This proposal is submitted by the ICC Building Code Action Committee (BCAC) The BCAC was established by the ICC Board of Directors to pursue opportunities to improve and enhance an assigned International Code or portion thereof. This includes both the technical aspects of the codes as well as the code content in terms of scope and application of referenced standards. Since its inception in July, 2011, the BCAC has held 3 open meetings and over 15 workgroup calls which included members of the BCAC as well as any interested party to discuss and debate the proposed changes. Related documentation and reports are posted on the BCAC website at: This proposal is a continuation of Item E5-09/10 that was approved for inclusion in the 2012 IBC. That is, the proposal intends to clarify current IBC means of egress requirements resulting in greater user friendliness and increased uniformity in the application of these important provisions. Currently, both Sections 1015 and 1021 contain provisions for the determination of the number of exits and exit access doorways. The relationship between the two sections is not particularly obvious to many code practitioners. This proposal combines the two sections and places their various provisions in technical context. This is partially achieved through formatting. Section prescribes the provisions for the determination of the number of required exits or exit access to exits from any individual space. Section provides the provisions for the determination of the number of required exits or access to exits from stories or occupied roofs. Recognizing the importance of tables during the design/review process, improvements were made to improve understanding and consistency. Fundamental to the proper determination of the number of required exits is the consideration of design occupant loads and occupant remoteness. Currently, only Table (2) includes both variables (number of occupants per story and exit access travel distance). Section currently addresses the occupant load in Table ; however, it requires the user to determine occupant remoteness requirements at Section that are indicated as common path of egress travel. For the 2012 Edition of the IBC, common path of egress travel provisions have been consolidated into a tabular format. The only remaining text of Section states, The common path of egress travel shall not exceed the common path of egress travel distances in Table , without contextual reference to Section that requires that two exits or exit access doorways from any space shall be provided where the common path of egress travel exceeds one of the limitations of Section This technical disconnect is repaired through the consolidation of Tables and in a format already contained in Table (2). The current difference in occupant remoteness terminology (exit access travel distance vs. common path of egress travel) was resolved in favor of common path of egress travel distance. To increase consistency in interpretations and application, the definition of COMMON PATH OF EGRESS TRAVEL has been modified. The proposed language emphasizes that the common path of egress travel is initially measured identically to exit access travel distance; however, technically terminates at an earlier point (that point where an occupant has separate and distinct access to two exits or exit access doorways vs. to an entrance to an exit). The somewhat vague wording in the current definition results in inconsistent applications of this important provision. It should be noted that the NFPA 101 Handbook states that common path of egress travel is a portion of the exit access travel distance. Many rely on that document to interpret IBC requirements. Additionally, the merging provision has been deleted. This is a moot point because once a second exit or exit access doorway (to include any point where an occupant enters an intervening room, corridor, exit access stairway or exit access ramp) is required, it must be separated in accordance with Section In recent code development cycles, many definitions have been edited to more accurately describe means of egress design requirements in context with the IBC system philosophy. This is another example of more accurately describing what is intended. The establishment of a single method and term for the determination of occupant remoteness will greatly benefit code practitioners. The resultant Table is consistent in format, terminology and application to Table (2) and will result in more accurate and consistent determination of the required number of exits and access to exits. This proposal deletes current Section , Exception 7. This provision was new to the 2009 Edition of the IBC and, according to the proponent s reason statement, was intended to coordinate the fragmented requirements of Sections 1015 and The consolidation of the two sections eliminates the need for the provision. The exception can be considered moot because 2012 ICC FINAL ACTION AGENDA 1044

9 it represents an exception to a non-requirement. There is no requirement for specific spaces to be accessed by the remainder of the story. The performance nature of number of exits/exit access provisions allows each space to be designed based on its own technical merit on an individual and collective basis. The conditions of the exception simply restate fundamental means of egress provisions. Based on the stated requirements of this proposal, the deleted exception is unnecessary. Formerly, both Sections 1015 and 1021 contained provisions for the determination of exit/exit access configuration/arrangement/separation. Inasmuch as this issue is a major means of egress design requirement, the provisions have been consolidated into a new stand-alone section, Section Additionally, separation measurement provisions have been clarified. Currently, there are no specific measurement points for the determination of exit/exit access separation. New Section provides guidance for measuring to doors, exit access stairways and exit access ramps. This will reduce subjectivity in the determination of exit/exit access configuration. Numbers of exits/exit access doorways and exit/exit access doorway configuration provisions have been located in Sections 1006 and 1007 respectively. This creates a sectional sequence for occupant load based means of egress provisions. Section 1004 covers design occupant load determination. Means of egress sizing requirements based on occupant load are contained in Section Now, occupant load based numbers requirements are placed in Section 1006 with multiple exit/exit access doorway arrangement provisions following in Section This logical format should assist designers and enforcement officials alike. It was also determined that a general exit provision addressing exit continuity is incorrectly located in current Section It has been properly located in Section In summary, this proposal represents a continuing effort to improve means of egress provisions for the purposes of philosophical functionality, technical consistency and user friendliness. Approval of this proposal will simplify the interpretation and application of IBC means of egress provisions while maintaining the highest traditions of fire and life safety. Cost Impact: This code change proposal will not increase the cost of construction E-BAJNAI-BCAC.docx Public Hearing Results Committee Action: Approved as Submitted Committee Reason: Consolidation of information for number of exits from a space and floor (Section 1015 and 1022) reduces duplication of language and should simplify the code for the users. The understanding on the common path of travel requirements should be enhanced. In the definition for common path of travel, by the addition of exit access doorways, there is concern that where two exit access doorways are available, that this could be interpreted as ending the common path of travel. Adding back into the definition, paths that merge are common path of travel would address the issue. There may also be a problem with proposed travel distance measurements in new Section Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment 1: Gregory R. Keith, Professional heuristic Development, representing The Boeing Company, requests Approval as Modified by this Public Comment. Modify the proposal as follows: COMMON PATH OF EGRESS TRAVEL. That portion of the exit access travel distance measured from the most remote point of each room, area or space within a story to that point where the occupants have separate and distinct access to two exits or exit access doorways. (Portions of code change remain unchanged) Commenter s Reason: This public comment is intended to clarify the intent of the definition for common path of egress travel. The original proposal was based on the last sentence of the 2012 IBC definition, Common paths of travel shall be included within the permitted travel distance. and the language in Section , Exit access travel distance shall be measured from the most remote point within a story The original E1-12 definition could be interpreted such that the common path or egress travel need be considered from only one point (the most remote) on a given story. Obviously, all potential paths of egress travel need to be considered when establishing occupant remoteness for the purposes of determining multiple exit or exit access doorway requirements. Clarifying that the path of travel originating from any room, area or space should be evaluated when determining common paths of egress travel will eliminate literal interpretations of the original definition. Additionally, the reference to a single story has been eliminated. Section allows for access to exits at an adjacent level. Common path of egress travel requirements could potentially apply to a multi-level design condition. Approval of this modification will clarify the definition of 2012 ICC FINAL ACTION AGENDA 1045

10 common path of egress travel for the benefit of all users. This modification is consistent with the 2012 means of egress requirements established by Item E5-09/10. Public Comment 2: William E. Koffel, P.E., Koffel Associates, Inc., requests Approval as Modified by this Public Comment. Modify the proposal as follows: COMMON PATH OF EGRESS TRAVEL. That portion of the exit access travel distance measured from the most remote point within a story to that point where the occupants have separate and distinct access to two exits or exit access doorways. Paths that merge are common paths of travel. Commenter s Reason: I testified in opposition to the proposed change to the definition of common path of egress travel in Dallas since the language proposed in E1 would allow the common path of egress travel measurement to stop at a point where occupants have separate and distinct access to two exits. For example, if a room has two exit access doorways one could stop measuring common path of travel at a point in the room where access to the two doors is by a separate and distinct path. However, if those doors lead to a dead-end corridor and the occupant needs to travel in one direction in the corridor, there is still a common path of travel. This issue was noted by the Committee in the Report of the Public Hearing: In the definition for common path of travel, by the addition of exit access doorways, there is concern that where two exit access doorways are available, that this could be interpreted as ending the common path of travel. Adding back into the definition, paths that merge are common path of travel would address the issue. The Public Comment has been submitted to address the concern I raised by including the solution recommended by the Committee. Public Comment 3: Lee J. Kranz, City of Bellevue Washington representing Washington Association of Building Officials Technical Code Development Committee, requests Approval as Modified by this Public Comment. Modify the proposal as follows: SECTION 202 DEFINITIONS COMMON PATH OF EGRESS TRAVEL. That portion of the exit access travel distance measured from the most remote point within a story to that point where the occupants have separate and distinct access to two exits or exit access doorways. Paths that merge are common paths of travel. Common paths of egress travel shall be included within the permitted travel distance (IFC [B] ) Measurement. The required separation distance between exits or exit access doorways shall be measured in accordance with the following: 1. The separation distance to exit or exit access doorways shall be measured to the nearest point along the width doorway. 2. The separation distance to exit access stairways shall be measured to the nearest point along the width of the closest riser. 3. The separation distance to exit access ramps shall be measured to the nearest point along the width of the start of the ramp run. Commenter s Reason: Code change E1-12 was approved by the Egress Committee in Dallas but there was discussion about the need to maintain the Paths that merge are common paths of travel text. This language is needed to clarify that merging paths are still counted as part of the common path of travel and the measurement continues until the point where two separated paths are available. The length of a common path of travel is limited to insure that occupants will not have to travel excessive distances to reach safety or to the point where if one path is compromised the other will be tenable. Section provides a more specific and precise method of measuring the required separation between exits or exit access points. The proposed changes to items #2 and #3 create consistency with the methodology used in item #1 of Section In the Hearings Results, the Committee action indicated that The understanding on the common path of travel requirements should be enhanced. In the definition for common path of travel, by the addition of exit access doorways, there is concern that where two exit access doorways are available, that this could be interpreted as ending the common path of travel. Adding back into the definition, paths that merge are common path of travel would address the issue. There may also be a problem with proposed 2012 ICC FINAL ACTION AGENDA 1046

11 travel distance measurements in new Section This public comment addresses the issues discussed at the Code Development Hearings for E1-12. Public Comment 4: Dennis Richardson, PE, CBO, City of Salinas, representing Tri-Chapter (Peninsula, East Bay and Monterey Chapters, ICC), requests Approval as Modified by this Public Comment. Modify the proposal as follows: SECTION 202 DEFINITIONS COMMON PATH OF EGRESS TRAVEL. That portion of the exit access travel distance measured from the most remote point within a story to that point where which the occupants are required to traverse before two have separate and distinct paths of egress travel access to two exits or exist access doorways are available. Paths that merge are common paths of travel. Common paths of egress travel shall be included within the permitted travel distance. (Portions of code change remain unchanged) Commenter s Reason: E1-12 makes improvements to clarify how the maximum occupant load in a space as well as the maximum common path of egress travel both contribute to determining whether or not a space needs two exits or exit access doors. E1-12 also introduced a new definition for Common Path of Egress Travel which was intended to increase the consistency in interpretations and application of the definition as follows: COMMON PATH OF EGRESS TRAVEL. That portion of the exit access travel distance measured from the most remote point within a story to that point where the occupants have separate and distinct access to two exits or exit access doorways. This definition creates additional confusion and needs more work in the next code cycle. This public comment proposes to replace the new definition with the existing definition of common path of egress travel. The balance of E1-12 remains unchanged. It is felt the current definition will continue to serve until improvements are made to what was proposed. The new definition approved as part of E1-12 will create more confusion as it refers to a specific instance within a story measured from the most remote point of the story as the only starting point to measure common path of egress travel (see point A in Example 1; E1-12 public comment example). This specific point could coincide with the common path of egress travel starting point but in most instances with different tenants or suites, the starting point to measure common path of travel from a space has nothing to do with the most remote point within a story (see point B in example 1; E1-12 public comment example). There often are multiple points in a story (different spaces) where the common path of egress travel could be critical (see Example 2; E1-12 public comment example). The intent of the common path of egress travel is to look at the entire exit access not just along the exit access travel distance path from just the most remote point within the story. There is a fatal flaw in the new definition approved along with E1-12. The definition should revert back to the previous definition until a new definition can be proposed in the next code cycle or is successfully updated by public comment in this cycle. Cost Impact: This code change will not increase the cost of construction ICC FINAL ACTION AGENDA 1047

12 Public Comment 5: Hope Medina and Kirk Nagle, Town of Castle Rock and City of Arvada, representing selves, requests Disapproval. Commenter s Reason: The new table is confusing, and lacking some clarity. In table there are several inconsistencies. R3 with a sprinkler has a maximum travel distance of 75 and a maximum travel distance of 100. I have no idea which one I should use. The original table was for the single exit requirement for mixed occupancies and table listed the common path of egress travel which was much less confusing. The R4 is listed with no values for maximum common travel distance with a sprinkler or without a sprinkler so I am assuming the distance is infinity. The R3 occupancy is only allowing a common path of egress when there is a sprinkler. The U occupancy is listing a without a sprinkler an occupant load of less than thirty a travel distance of 100 but with a sprinkler a travel distance of 75: not sure how to determine what occupant load to use here.. The values do not offer clarity and make this table unusable. In exception 1 has one means of egress with an occupant load of 20 when equipped with a fire sprinkler system list the common path of egress as 125 feet which conflicts with the maximum occupant load is 10 with a travel distance of 125 feet, and it also conflicts with a maximum occupant load of 10 with a travel distance of 75 feet. This code needs to be rewritten to be useful. This code change does not repair any current issues in fact it creates more confusion for the code user.

Buildings for pumps or for shelter of loading personnel are allowed to be part of the loading rack. Wiring and electrical equipment located within 25 feet (7620 mm) of any portion of the loading rack shall be in accordance with Section Reason: The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. The intent is for the consistent use of the defined terms for stair and stairway throughout the all the codes. Stair is used when talking about individual steps or stepped aisles. Stairway is used when the provisions are applicable to a series of steps, or flights and landings between stories. In addition, when terms such as exit access stairway and exit access ramp follow each other in a list, consistently eliminate a couple of words by saying exit access stairway and ramp. When the provisions are equally appropriate for ramps and stairways, ramps is added. Cost Impact: None 202-E-BALDASSARRA-CTC.DOC Public Hearing Results PART III IFC Committee Action: Approved as Submitted Committee Reason: The proposal revised the use of stair and stairway throughout the code so that the application matches how the defined terms. This will clarify when requirements are intended for a change in elevation (i.e., stair) vs. a change in story (i.e., stairway). There was a question from the committee whether in Section , Item 7 should include exterior exit stairway. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee, requests Approval as Modified by this Public Comment Modify the proposal as follows: IFC (IBC [F] ) Required features. The fire command center shall comply with NFPA 72 and shall contain the following features: 1. through 6. (no change) 7. Controls for unlocking interior exit stairway doors simultaneously. 8. through 18. (no change) (Portions of proposal not shown remain unchanged.) Commenter s Reason: The modification to IFC Section (IBC ) Item 7 is due to a concern brought up by one of the Means of Egress Code Development committee regarding possible fire department access requirement from exterior exit stairways when dealing with locked exit stairway doors. The proposal is to not add the words interior exit so that the requirement for unlocking would be the same for interior exit stairways as exterior exit stairways. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as Areas of Study. The Area of Study for this code change and public comment is called Unenclosed exit stairways. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-four meetings all open to the public.

These walls (both bearing and non-bearing) are depended upon to: a) contain a fire within the building of origin; or b) keep an exterior fire outside the building. It is therefore important to indicate on the drawings where any openings are located as well as the materials and construction of all doors or shutters. The drawings should indicate the presence of wired glass, its thickness and framing, and identify the materials used for windows and door frames. The protection of openings adjacent to exterior means of escape (e.g., exterior stairs stairways, fire escapes) is particularly important. The ground floor drawing should locate the building on the property and indicate the precise distances to adjacent buildings. The field investigator should be alert for differences in function as well as in materials and construction details. In general, the details within apartments are not as important as the major exit paths and stairwells exit stairways. The preliminary field investigation should attempt to determine the thickness of all walls. A term introduced below called thickness design will depend on an accurate (± 1/4 inch) determination. Even though this initial field survey is called preliminary, the data generated should be as accurate and complete as possible. The field investigator should note the exact location from which observations are recorded. For instance, if a hole is found through a stairwell wall enclosing an exit stairway which allows a cataloguing of the construction details, the field investigation notes should reflect the location of the find. At the preliminary stage it is not necessary to core every wall; the interior details of construction can usually be determined at some location. Doors: Doors to stairways and hallways represent some of the most important fire elements to be considered within a building. The uses of the spaces separated largely controls the level of fire performance necessary. Walls and doors enclosing stairs stairways or elevator shafts would normally require a higher level of performance than between a the bedroom and bath. The various uses are differentiated in Figure 1. Rule 7: The fire endurance of asymmetrical constructions depends on the direction of heat flow. This rule is a consequence of Rules 4 and 6 as well as other factors. This rule is useful in determining the relative protection of corridors and stairwells walls enclosing an exit stairway from the surrounding spaces. In addition, there are often situations where a fire is more likely, or potentially more severe, from one side or the other. Reason: The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. The intent is for the consistent use of the defined terms for stair and stairway throughout the all the codes. Stair is used when talking about individual steps or stepped aisles. Stairway is used when the provisions are applicable to a series of steps, or flights and landings between stories. In addition, when terms such as exit access stairway and exit access ramp follow 2012 ICC FINAL ACTION AGENDA 1066

31 each other in a list, consistently eliminate a couple of words by saying exit access stairway and ramp. When the provisions are equally appropriate for ramps and stairways, ramps is added. PART I IBC MEANS OF EGRESS Committee Action: Approved as Submitted Committee Reason: The proposal revised the use of stair and stairway throughout the code so that the application matches the defined terms. This will clarify when requirements are intended for a change in elevation (i.e., stair) vs. a change in story (i.e., stairway). There was some concern about the style choice to say exit access stairway and ramp vs. using the specific defined terms exit access stairways and exit access ramps.

Where more than one exit or exit access point doorway is required, the exit access shall be arranged such that there are no dead ends in corridors more than 20 feet (6096 mm) in length. Exceptions: 1. In occupancies in Group I-3 of Occupancy Condition 2, 3 or 4 (see Section 308.5), the dead end in a corridor shall not exceed 50 feet ( mm). 2. In occupancies in Groups B, E, F, I-1, M, R-1, R-2, R-4, S and U, where the building is equipped throughout with an automatic sprinkler system in accordance with Section , the length of the dead-end corridors shall not exceed 50 feet ( mm). 3. A dead-end corridor shall not be limited in length where the length of the dead-end corridor is less than 2.5 times the least width of the dead-end corridor (IFC [B] ) Assembly aisles are required. Every occupied portion of any building, room or space used for assembly purposes that contains seats, tables, displays, similar fixtures or equipment shall be provided with aisles leading to exits or exit access points doorways in accordance with this section. Aisle accessways for tables and seating shall comply with Section Reason: The term exit access doorway is a misnomer. By definition, the term exit access doorway includes any access point along the path of egress travel including exit access stairways and ramps. Given the literal nature of the term doorway, without consulting the definition, most code users would not necessarily associate stairways and ramps when they read the word doorway. This distinction becomes important with the 2012 Edition of the IBC. E5-09/10 introduced the terms exit access stairway and exit access ramp into Chapter 10. These definitions are particularly significant because the concept of accessing exits at an adjacent story by way of exit access stairways and ramps has been formalized in the 2012 IBC. There are several requirements that relate to the establishment of these terms. For instance, Section states, Exit and exit access doorways shall be arranged in accordance with Sections and It is important that required exits and exit access stairways serving a given story are properly separated. The fact that the requirement refers only to exits and exit access doorways can be misleading. By requiring the separation of exits and exit access points, it is clear to code practitioners that any specified exit access component, whether it be a door, doorway, exit access stairway or exit access ramp, must comply with the provision. It is not in the best interests of either the design or enforcement communities for the IBC to be misleading through its terminology. It is imperative that the IBC articulate what is intended in the clearest fashion possible. This is particularly important at a time when the IBC means of egress definitions and provisions are being technically and editorially adjusted. Approval of this proposal will increase uniformity in the application of fundamental means of egress provisions.

36 Public Hearing Results Committee Action: Disapproved Committee Reason: The committee felt that this new term might confuse the issue rather than clarify this for code users. Exit access points would be confusing when looking at exit sign placement, locations of pull stations. The committee was concerned that the use of this term may possibly reduce the concept of compartmentation or blur the line for measurement of where to measure travel distance.

Day care facilities, rooms or spaces where care is provided for more than 10 children that are 2-1/2 years of age or less, shall have access to not less than two exits, or exit access doorways or exit access points (IFC [B] ) Dead ends. Where more than one exit, or exit access doorway or exit access point is required, the exit access shall be arranged such that there are no dead ends in corridors more than 20 feet (6096 mm) in length. Exceptions: 1. In occupancies in Group I-3 of Occupancy Condition 2, 3 or 4 (see Section 308.5), the dead end in a corridor shall not exceed 50 feet ( mm). 2.

Aisle accessways for tables and seating shall comply with Section Commenter s Reason: Based on means of egress code committee comments that the new term, exit access point, might confuse code users with respect to exit sign placement and locations of pull stations, the definition of exit access doorway has been restored. The original reason for the proposal submittal was that the current definition of EXIT ACCESS DOORWAY contained additional exit access components; specifically, exit access stairways and exit access ramps. Those terms are independently defined in the IBC and need not be included in the definition of exit access doorway. A new term exit access point is created for purposes of technical clarification and is intended to identify how to accurately determine numbers of required exits or access to exits from spaces and exit/exit access configuration. The term is integrated into Section 1015 and helps to indicate what combination of means of egress components may be used to satisfy the various requirements contained in that section. For instance, Section presently requires separation between exits and exit access doorways. Based on the current definition of exit access doorway, exit access stairways and ramps would also be required to be properly separated. As a matter of practice, most code practitioners do not normally consult definitions and that technical subtlety might be lost. The creation of a definition for EXIT ACCESS POINT and the reference to that term in applicable sections will assist design professionals and code enforcement officials and result in more consistent interpretation and application of these fundamental provisions. This public comment has addressed the concerns of the means of egress committee. E3-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1074

39 E , (IFC [B] ) Proposed Change as Submitted Proponent: Gregory R. Keith, Professional heuristic Development, representing The Boeing Company Revise as follows: SECTION 202 DEFINITIONS EXIT ACCESS RAMP. An interior ramp that is not a required interior or exterior exit ramp. EXIT ACCESS STAIRWAY. An interior stairway that is not a required interior or exterior exit stairway. EXTERIOR EXIT RAMP. An exit component that serves to meet one or more means of egress design requirements, such as required number of exits or exit access travel distance, and is open to yards, courts or public ways. EXTERIOR EXIT STAIRWAY, EXTERIOR. An exit component that serves to meet one or more means of egress design requirements, such as required number of exits or exit access travel distance, and is open to that is open on at least one side, except for required structural columns, beams, handrails and guards. The adjoining open areas shall be either yards, courts or public ways. The other sides of the exterior stairway need not be open. INTERIOR EXIT RAMP. An exit component that serves to meet one or more means of egress design requirements, such as required number of exits or exit access travel distance, and provides for a protected path of egress travel to the exit discharge or public way. INTERIOR EXIT STAIRWAY. An exit component that serves to meet one or more means of egress design requirements, such as required number of exits or exit access travel distance, and provides for a protected path of egress travel to the exit discharge or public way. RAMP. A walking surface that has a running slope steeper than one unit vertical in 20 units horizontal (5- percent slope). STAIRWAY. One or more flights of stairs, either exterior or interior, with the necessary landings and platforms connecting them, to form a continuous and uninterrupted passage from one level to another. STAIRWAY, INTERIOR. A stairway not meeting the definition of an exterior stairway. Revise as follows: (IFC [B] ) Open side. Exterior exit stairways and ramps serving as an element of a required means of egress shall be open on at least one side, except for required structural columns, beams, handrails and guards. An open side shall have a minimum of 35 square feet (3.3 m 2 ) of aggregate open area adjacent to each floor level and the level of each intermediate landing. The required open area shall be located not less than 42 inches (1067 mm) above the adjacent floor or landing level. Reason: Several new means of egress terms were created and defined in the 2012 Edition of the International Building Code. They include, EXIT ACCESS STAIRWAY, EXIT ACCESS RAMP, INTERIOR EXIT STAIRWAY and INTERIOR EXIT RAMP. These, and other terms, are fundamental to the design of any means of egress system. There is a precise relationship between these terms. It is proposed to modify the definition of both EXIT ACCESS STAIRWAY and EXIT ACCESS RAMP by deleting the 2012 ICC FINAL ACTION AGENDA 1075

40 word interior. This is appropriate in that the exit access can be exterior to the building and changes in floor level can occur along the path of egress travel. Since an exit access stairway or ramp can be interior or exterior to the building, it is clarified that they are not exterior exit stairways or ramps as well. Exterior exit stairways and exterior exit ramps are exit components according to the definition of EXIT in Section 202 and Section Both of these terms are currently undefined in the IBC. There is, however, a definition for STAIRWAY, EXTERIOR. An exterior stairway is not a means of egress component, per se, in the IBC. It is proposed to replace the definition of STAIRWAY, EXTERIOR with a definition for EXTERIOR EXIT STAIRWAY. The proposed definition is consistent with the current definition except for the distinction that such stairways are open to yards, courts or public ways consistent with the requirements in Section Additionally, Section has been modified to add technical language formerly contained in the definition of STAIRWAY, EXTERIOR as regards in impact of structural columns, beams, handrails and guards on openness determination. A companion definition for exterior exit ramps has been created which is consistent with the proposed definition of exterior exit stairway. Lastly, it is proposed to delete the current definition of STAIRWAY, INTERIOR. This definition is nonsensical, obsolete and out of current technical context. The current definition of "EXIT ACCESS STAIRWAY" effectively replaces this definition. The definitions of INTERIOR EXIT RAMP, INTERIOR EXIT STAIRWAY. RAMP and STAIRWAY have been included for reference purposes so the relationship of the various terms can be seen. In summary, the proposed modifications to these means of egress component definitions will provide necessary clarity for users who are designing or analyzing a means of egress system. It is imperative that IBC definitions be technically accurate and properly descriptive. Approval of this proposal will allow for more consistent interpretations and applications of important IBC means of egress provisions. Cost Impact: None 202-Exit access doorways-e-keith.doc Public Hearing Results Committee Action: Disapproved Committee Reason: There was a concern that ramps or stairways within the exit discharge would fall within the definition of exit access ramps and stairways. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Gregory R. Keith, Professional heuristic Development, representing The Boeing Company, requests Approval as Modified by this Public Comment Modify the proposal as follows: EXIT ACCESS RAMP. A ramp within the exit access portion of the means of egress system that is not a required interior or exterior exit ramp. EXIT ACCESS STAIRWAY. A stairway within the exit access portion of the means of egress system that is not a required interior or exterior exit stairway. (Portions of proposal not shown remain unchanged.) Commenter s Reason: The ICC Means of Egress Code Development Committed disapproved Item E4-12 at the 2012 ICC code development hearings in Dallas, Texas. In its published reason statement, the committee noted, There was a concern that ramps or stairways within the exit discharge would fall within the definition of exit access ramps and stairways. Based on that comment, and the fact that the concern was over current text, the proposed definitions for exit access stairways and exit access ramps have been revised to indicate that exit access stairways and ramps occur within the exit access portion of the means of egress system. Given that the formal technical relationship between exit access stairways and ramps and interior exit stairways and ramps has 2012 ICC FINAL ACTION AGENDA 1076

41 been established in the 2012 Edition of the IBC, it is important that these key definitions accurately describe their role in the proper design of a means of egress system.

The provisions of this section shall apply to shafts required to protect openings and penetrations through floor/ceiling and roof/ceiling assemblies. Exit access stairways and exit access ramps shall be protected in accordance with the applicable provisions of Section Interior exit stairways and interior exit ramps shall be protected in accordance with the requirements of Section Reason: The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. The most substantial part of this change is the relocation of exit access specific stair requirements from the general stair section 1009 to a stand alone section Another substantial purpose of this code change proposal is for coordination between the open stairway code change from this committee for the last cycle (E5-09/10) and other changes that occurred during the same cycle. In addition, there were areas that needed to be clarified as part of coordination. The CTC also reviewed the concerns raised in the E5 09/10 Public Comments and addressed some outstanding issues from the public comments. Below are the specific reason statements for each section proposed for change: 202 (and exception #3)-The word interior was deleted from the definition of exit access stairway and ramp. Generally, this is done because there is no need to restrict exit access to interior elements. Specifically, this was done in coordination with the proposed deletion of exception #3 to section Exception #3 was a holdover from when what are currently exit access stairs were exit stairs. Exception #3 was there to coordinate the allowance for an exterior exit stair to be unprotected when an interior exit stair would be allowed to be unprotected. E5 changed the unenclosed exit stair to an exit access stair. In keeping with that methodology this exception is being deleted and interior is being removed from the exit access stair and ramp definitions so that the provisions that allow an unenclosed exit access stair are equally applicable to interior or exterior stairways. Rather than use exception #3 to for a exterior stair without protection the exit access provisions would be used for the exterior stair The new sentence in was a requirement in two sentences in that is proposed to be relocated here as it is a more general requirement. This was done as part of some additional proposed revisions to section that will be explained below in section order This is another coordination change related to the relocation of the access stair provisions from to The last sentence of the main paragraph states that exit access stairways connecting levels in the same story are not permitted as part of an accessible means of egress. While this is true for split level floors or stepped aisles, this should not be true for mezzanines. While they are considered part of the floor below for height and area requirements, mezzanines are required to be elevated over 7-0 (Section 505.2) similar to a story change in level ICC FINAL ACTION AGENDA 1087

52 The exception should only apply to exit stairways based on mandatory enclosure requirements for exit stairways. Exit access stairs may be open or enclosed with non-rated enclosures therefore the requirement needs to be clear that separation of areas of refuge serving exit access stairways must comply with , and subsections This proposed change will remove the specific requirements for exit access stairways for the general stairway section will remain a general stair design section for all stairway details that are not means of egress system specific such as tread and riser dimensions, headroom, widths, etc. The specific enclosure requirements regarding exit access stairs are proposed to be addressed in a new stand alone section, This is in keeping with the same organization already in chapter 10 for the specific protection requirements for interior exit stairways and ramps and exterior exit stairways and ramps, as well as exit passageways and horizontal exits, each having a dedicated section that addresses the specific protection requirements for each means of egress element. The idea is to separate the general requirements from the specific requirements with regards to each type of MOE element through These sections explain how to construct a rated shaft enclosure around an exit access stair when a fire rating is required based on floor penetration limits being exceeded to prevent vertical smoke and heat migration. They were deleted entirely and not relocated to 1018 because the new sections and are proposed to reference to Section 713 for floor opening enclosure construction requirements. The original concept in E5 09/10 was to repeat the shaft enclosure requirements in the exit access stair section as exit access stair enclosure construction requirements. It was decided that this added unneeded text to the code and because it was a duplicate of requirements based on 713 that a change to one section may not be made to the companion section and therefore has the potential to set up an inconsistency with the two code sections that are intended to be the same This section is proposed to be deleted because it is not necessary. Just as 1009 is the general requirements for stairs 1010 is the general requirements for ramps. The specific requirements are addressed in stand alone sections that do not need to be cross referenced from the general section or vise versa Exit access doors is proposed for deletion in the first sentence because marking the path of egress travel is addressed in the remainder of section and exit access doors are part of the path of egress travel Revised to include mezzanines to clarify a mezzanine is a space, not a story, for purposes of means of egress. This also clarifies the 2012 IBC revision to Section 505 where mezzanines now reference Chapter 10 for means of egress Egress was deleted from the 2009 edition and replaced with , which is just a reference to chapter The second sentence was moved to because it is a more general requirement. Exit access stairways and ramps is proposed to be added to the third sentence because by definition an exit access doorway is a point where a path of travel enters an unenclosed exit access stairway but not the stairway itself. Therefore, current code text will allow exit access stairs to diverge towards each other reducing the distance between the stairways to less than the minimum separation. This is the beginning of a few changes to section 1015 that will prohibit diverging exit access stairs to less than the required separation distance for exit access doorways. Further modifications detailed below detail arrangement of exit access stairways in addition to exit access doorways, therefore, the elements were added to for consistency with the next proposed changes to and and In three places the word doors was deleted after exit because exit stands on its own and does not need to specifically reference and exit door When exit access stairs are used the point where the path of travel enters the stairway is by definition an exit access doorway. There is concern that there will be confusion regarding how to measure the distance between exit access doorways when unenclosed exit access stairways are used. The three measurement methods are proposed to be added to clearly state how to measure between doors, stairways and ramps when they need to meet separation requirements per section and This proposed section and sub-section are intended to require that the minimum separation distances between exit access stairways and ramps be maintain for the entire length of travel on the stairway or ramp. This is to prohibit stair and ramp runs that meet separation distance requirements at the first riser or beginning slope, from converging towards another stair or ramp such that the separation is reduced as the occupant goes up or down the stair or ramp run. Exit access stairs and ramps should maintain the required distance, just as doors, until egress travel over the ramp or stair is completed This is a companion change to exception #6 (pervious #7 to ) detailed below regarding outdoor facilities. The exception to was changed to match the requirements for open air seating as regulated by section , which allows unlimited travel distance in non-combustible construction that has open air seating and 400 feet in combustible construction. This change deletes the measurement of the travel distance to the closest riser in outdoor facilities and replaces it with the 400 foot or unlimited travel distance per The intent is to coordinate the various travel distance requirements regarding open air seating facilities. New Section 1018 Exit access stairways and ramps- Current section is proposed to be relocated to new section This is the most significant aspect of this code change proposal. This part of the proposed change creates a new stand alone code section for exit access stairway and ramp specific requirements so that the specific requirements for exit access stairs are separate from the general requirements. This is in keeping with the same organization already in chapter 10 for the specific protection requirements for interior exit stairways and ramps and exterior exit stairways and ramps, as well as exit passageways and horizontal exits, each having a dedicated section that addresses the specific protection requirements for each means of egress element. The specific enclosure requirements regarding exit access 2012 ICC FINAL ACTION AGENDA 1088

53 stairs are proposed to be addressed in the new section, will remain a general stair design section for all stairway details that are not means of egress system specific such as tread and riser dimensions, headroom, widths, etc. New This is just a general scoping section. The statement that stories include basements but not mezzanines was included in this section. New This section clarifies that steps/ramps between levels within a story are always permitted to be open. Enclosure requirements are not required until openings between stories are created for exit access stairways/ramps. New (relocated ) This proposed section is the text relocated from with some changes to the format and some changes to the specific exemptions. The code change text is formatted with underlines and strike-troughs of the relocated text. Each specific change is explained as follows: New As an alternative to the rule with exceptions format the section was reformatted with the exceptions reconfigured as conditions which permit unprotected floor openings for exit access stairs/ramps. This is in keeping with the philosophy introduced with the vertical openings code change approved for the 2012 edition, which reconfigured the shaft enclosure exceptions to options. As part of the reformatting the statement not required to be enclosed has been removed from the exceptions to the body of section Additionally and ramps has been added to each condition; this was done to make it clear that the entire section addresses ramps and stairs equally. Previous section and through were the enclosure requirements applicable when a floor opening is required to be protected with a fire rated enclosure; this was deleted and not relocated to These sections were deleted entirely and not relocated to 1018 because the new sections and are proposed to reference to Section 713 for floor opening enclosure construction requirements. The original concept in E5 09/10 was to repeat the shaft enclosure requirements in the exit access stair section as exit access stair enclosure construction requirements. It was decided that this added unneeded text to the code and because it was a duplicate of requirements based on 713 that a change to one section may not be made to the companion section and therefore has the potential to set up an inconsistency with the two code sections that are intended to be the same Exception/condition #1-Group I-2 and I-2 deleted from condition #1 and moved down to a new Section , which addresses group I-2 and I-1. The restriction that requires all group I-2 and I-3 stairway floor openings to be protected with a shaft has not been changed. The last sentence stating such interconnected stories shall not be open to other stories was added to clarify that the first condition can only be used when there are no openings to other stories, other than the two stories connected by the exit access stair. This is to prevent other permitted floor openings from being used with this allowed opening to create a staggered opening condition where more than two stories can atmospherically communicate Exception/condition #2-The use group limitation of this condition was moved from the end of the sentence to the beginning to make it easier to use so the code user can quickly identify the scope of the condition. Additionally live/work unit was added to the types of units that can use this condition. Unenclosed exit access stairs are permitted in live/work units per and live/work unit is a type of group R-2 unit distinct from dwelling units and sleeping units Exception/condition #3 and Deletion of exception #4-The term floor opening was replaced with vertical opening because the opening in this condition can be between multiple floors. Exception #4 was the same exception as exception #3 except that it applies to groups other than B and M with the only difference being that the opening is limited to 4 stories for groups other than B and M. To reduce the amount of text and number of conditions the other than group B and M provision was moved to condition #3 as the last sentence in condition # Exception/condition #4 and #5-Just reformatting as described in the general explanation Exception/condition #6- This condition was modified with input from Ed Roether, who is an expert in stadium design. Outdoor facilities where all portions of the means of egress are essentially open to the outside is proposed to be changed to openair seating, which is the term used in section regarding travel distance in assembly seating. This condition is proposed to be changed to be coordinated with the requirements for open air seating as regulated by section , which allows unlimited travel distance in non-combustible construction that has open air seating and 400 feet in combustible construction previous exception #8-This exception was deleted because the 2012 IBC section was modified to address the specific means of egress requirements for stages and technical production areas. New section in the 2012 IBC specifically exempts stage and technical production areas from stair/ramp enclosure therefore this exception/condition is redundant and not needed Exception/condition #7-Just reformatting as described in the general explanation previous exception #10 deleted This exception was moved to New This is the relocated and reformatted requirement for group I-2 and I-3 exit access stair/ramp enclosure as part of the reformat from exceptions to conditions. Additionally, as noted above, the previous exception #10 was relocated as an exception to this requirement because it is a specific exception for group I Exception #3 deletion exception #3 was a holdover from when what are currently exit access stairs were exit stairs. Exception #3 was there to coordinate the allowance for an exterior exit stair to be unprotected when an interior exit stair would be allowed to be unprotected. E5 changed the unenclosed exit stair to an exit access stair. In keeping with that methodology this exception is being deleted and interior is being removed from the exit access stair and ramp definitions so that the provisions that 2012 ICC FINAL ACTION AGENDA 1089

54 allow an unenclosed exit access stair are equally applicable to interior or exterior stairways. Rather than use exception #3 to for to create an exterior exit stair without protection the exit access provisions would be used for the exterior stair exception #1.1-This is an editorial change that clarifies the exit stairways/ramps must have the free path of travel. This is a companion to the new section 1.4 described below exception #1.4-This limitation is proposed to prevent an exit access stair and separate exit stair, which begin on the same floor, from termination to close together on the exit discharge floor. This is proposed so that one localized fire event on the exit discharge floor will not take out the termination of both means of egress components when an exit stair is permitted to discharge into the building. The 30 feet or ¼ diagonal separation distances were based on the 30 feet or ¼ diagonal that is specified for separation of interior stairways in high-rise section and and at least one leading directly to an exit is proposed for deletion. ICC staff asked for the committee to look at this do to numerous interpretive questions regarding what leading directly to an exit means. In both of these cases exit access stairs serving 2 stories could meet exception #1 and since neither condition qualifies as a story allowing exit access stairways is consistent with the provisions of Since directly to an exit can be interpreted to mean the mezzanine floor or balcony must have at least one exit at the mezzanine or balcony level that text is proposed to be deleted to allow exit access stairs to be used in both cases for both sets of stairways This is in response to E5 public comments. The intent of the separation required by this section is specific to the enclosure, not the stairway, therefore this language has been corrected See reason statement for and These changes are to coordinate with the change in section numbering that occurred with moving the exit access stairway and ramp provisions from 1009 to 1018 and the change to reference section 713 for exit access stairway and ramp rated enclosure design requirements. References related to if an enclosure is required refer to sections in 1018, which is where the requirements for when a rated enclosure is required are proposed to be relocated. References related to the construction of the rated enclosure refer to section 713, which is where the requirements for how to rate the enclosure are located References to exit access stairways and ramps are proposed to be removed from this section because section 1018 is proposed to reference section 713 for exit access stairway and ramp rated enclosure design. Existing section addresses prohibited openings therefore this reference is no longer needed in section See reason statement for above Criteria #2 was proposed to be deleted and was approved to be deleted in E5 09/10 but was inadvertently reinstated do to a language change proposed to the same text in FS 56 09/10. Floor openings for open exit access stairways are intended to be protected in accordance with the exit access stair provision in (1018 per this proposal). If Criteria #2 is retained it will cause inconsistency with the exit access stairway provisions. It was the intent of E5 09/10 to have all exit access stair related opening protection requirements provided in the exit access stair provisions in chapter This section has the terminology updated from unenclosed to exit access stairway to coordinate with terminology approved in E5-09/10. Additionally the section references are updated from to 1018 to coordinate with the relocation of exit access stair provisions from to 1018, which is explained further below in the reason statement. The purpose of the section is to act as a pointer to the exit access stairway vertical opening requirements that are all provided in proposed section 1018 (previous section ) for any vertical opening that contains an exit access stairway This is another coordination change related to the relocation of the access stair provisions from to The enclosure requirements for exit access stairways in 1018 now reference Section 713 for rated enclosure construction requirements, rather than repeating the requirements in chapter 10, therefore this sentence is no longer needed. Cost Impact: None 1009-E-BALDASSARRA Public Hearing Results Committee Action: Approved as Modified Modify proposal as follows: (IFC [B] ) Minimum requirements. It shall be unlawful to alter a building or structure in a manner that will reduce the number of exits or the capacity of the means of egress to less than required by this code. Means of egress shall be designed to be continuous and unobstructed (IFC [B] ) Exit or exit access doorway arrangement. Required exits shall be located in a manner that makes their availability obvious. Exits, exit access doorways, and exit access stairways and ramps shall be arranged in accordance with Sections and this section ICC FINAL ACTION AGENDA 1090

55 (IFC [B] ) Two exits or exit access doorways. Where two exits, or exit access doorways, and exit access stairways or and ramps, or any combination thereof, are required from any portion of the exit access, the exit or exit access doorways and exit access stairways and ramps they shall be placed a distance apart equal to not less than one-half of the length of the maximum overall diagonal dimension of the building or area to be served measured in a straight line between exit or exit access doorways and exit access stairways and ramps them. Interlocking or scissor stairs shall be counted as one exit stairway. Exceptions: 1. Where interior exit stairways are interconnected by a 1-hour fire-resistance-rated corridor conforming to the requirements of Section 1018, the required exit separation shall be measured along the shortest direct line of travel within the corridor. 2. Where a building is equipped throughout with an automatic sprinkler system in accordance with Section or , the separation distance of the exit or exit access doorways, and exit access stairways and ramps shall not be less than one-third of the length of the maximum overall diagonal dimension of the area served. Committee Reason: The committee proposed a modification to Section is to remove the proposed last sentence. That language is not needed as it is already included in the definition for means of egress. The modification to Section and was proposed by the proponent due to a grammatical error. The revised proposal will allow for all four components, 1) exits, 2) exit access doorways, 3) exit access stairways, and 4) exit access ramps, sot be considered when evaluating arrangements of exit access elements. The remainder of the proposal is a good cleanup related to the open stairway change, E5-09/10. The deletion of the separation (1009.3) requirements in favor of a reference to stairway separation requirements (Section 713 in new Section ) removes redundant language and will allow for consistency in the future. The new Section 1018, as a section for exit access stairway separation, is consistent with the idea of interior exit stairway separation in Section 1022 and exterior exit stairway separation in Section The new language regarding convergence of open exit stairways addressed this safety concern in an appropriate manner (1027.1). Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Al Godwin, CBO, CPM, representing Aon Fire Protection Engineering Corporation, requests Approval as Modified by this Public Comment. Further modify the proposal as follows: SECTION 1011 (IFC [B] 1011) EXIT SIGNS (IFC [B] ) Where required. Exits and exit access doors shall be marked by an approved exit sign readily visible from any direction of egress travel. The path of egress travel to exits and within exits shall be marked by readily visible exit signs to clearly indicate the direction of egress travel in cases where the exit or the path of egress travel is not immediately visible to the occupants. Intervening means of egress doors within exits shall be marked by exit signs. Exit sign placement shall be such that no point in an exit access corridor or exit passageway is more than 100 feet ( mm) or the listed viewing distance for the sign, whichever is less, from the nearest visible exit sign. Exceptions: 1. Exit signs are not required in rooms or areas that require only one exit or exit access. 2. Main exterior exit doors or gates that are obviously and clearly identifiable as exits need not have exit signs where approved by the building official. 3. Exit signs are not required in occupancies in Group U and individual sleeping units or dwelling units in Group R-1, R- 2 or R Exit signs are not required in dayrooms, sleeping rooms or dormitories in occupancies in Group I In occupancies in Groups A-4 and A-5, exit signs are not required on the seating side of vomitories or openings into seating areas where exit signs are provided in the concourse that are readily apparent from the vomitories. Egress lighting is provided to identify each vomitory or opening within the seating area in an emergency. Commenter s Reason: The original proposal deleted the phrase and exit access doors. These are the exit access doors out of rooms, offices, banquet halls, conference rooms, etc. Exit signs have always been required at these locations unless complying with the exceptions. The term Exits is not inclusive of exit access doors ICC FINAL ACTION AGENDA 1091

56 Without this phrase, exit signs will only be required in the exit access in cases where the exit or path of egress travel is not immediately visible. As such, each room has to be evaluated as to whether exit signs are needed. The phrase should be left in. E7-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1092

57 E (New) [IFC [B] (New)] Proposed Change as Submitted Proponent: Eric Astrachan, Executive Director, Tile Council of North America, Inc. Add new text as follows: (IFC [B] ) Ceramic and Porcelain Tile. Tiles specified for interior floor surfaces of the means of egress shall comply with ANSI A137.1, Section Reason: Currently, Section requires that walking surfaces of the means of egress be "slip resistant" with no method of measurement, quantitative threshold, or general principles to help the specifier, end-user, and code official. The purpose of this revision is to provide these criteria for ceramic tiles used for interior floor surfaces of the means of egress. Section of the ANSI A standard for ceramic tile sets forth a quantitative minimum threshold, means of measurement, and general principles regarding slip resistance based on the consensus of a broad range of stakeholders. Cost Impact: None (New)-E-Astrachan.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The edition of the standard referenced is not yet available in print. The standard is only for ceramic and porcelain tile. It seems inappropriate to require one type of flooring materials to meet slip resistance requirements and not others. It might possibly be interpreted that other types of floor finishes were not permitted in certain locations. Field testing would require a special device that most code official will not have. Third party testing might not always be an option. If tiles manufactured in the United States already meet this standard, is this information part of their standard product information? That would be needed for code officials to be able to verify compliance with this proposed requirement. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Eric Astrachan, Executive Director, Tile Council of North America, Inc. requests Approval as Submitted. Commenter's Reason: If the proposed change is not approved, Section will continue to require walking surfaces of the means of egress to be "slip resistant" with no method of measurement, quantitative threshold, or general principles to help the specifier, end-user, and code official. As expressed in our original proposal, the proposed change establishes these criteria for ceramic tile and porcelain tiles used for interior floor surfaces of the means of egress by referencing the relevant section (Section ) of the standard for ceramic tile, ANSI A During the Development Hearing, members of the Means of Egress Code Committee spoke favorably regarding the criteria proposed but were concerned that the edition of the referenced standard was not yet available in print. Members of the Committee expressed their reluctance that the proposal had to be disapproved for this reason by a very close 8 to 7 vote and strongly encouraged its resubmission for consideration once the published version of the standard is available. Other concerns had to do with establishing if the information needed by code officials would be part of standard product information. In August 2012 ANSI A will be available in its published form (draft copies are available now). Further, the criteria proposed (Section from ANSI A ) will also be included in its entirety in the 2013 TCNA Handbook for Ceramic, Glass, and Stone Tile Installation (commonly known as the TCA Handbook and referenced in Section 9300 specifications) ICC FINAL ACTION AGENDA 1093

58 Additionally, tile manufacturers are already providing the information needed by code officials as part of standard product information. Links to manufacturer catalogs confirming such can be provided if desired. With the concerns of the Committee addressed, we respectfully request that E12-12 should be approved as originally submitted (AS). E12-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1094

Keith, Professional heuristic Development, representing The Boeing Company Revise as follows: (IFC [B] ) Means of egress continuity. The path of egress travel along a means of egress shall not be interrupted by any building element other than a means of egress component as specified in this chapter. Obstructions shall not be placed in the required width of a means of egress except projections permitted by this chapter. The required capacity of a means of egress system shall not be diminished along the path of egress travel (IFC [B] ) Areas without fixed seating. The number of occupants shall be computed at the rate of one occupant per unit of area as prescribed in Table For rooms, areas or spaces without fixed seating, the occupant load shall not be less than that number determined by dividing the floor area under consideration by the occupant load factor assigned to the function of the space as set forth in Table Where an intended function is not listed in Table , the building official shall establish a function based on a listed function that most nearly resembles the intended function. (Renumber subsequent sections) (IFC [B] ) General. All portions of the means of egress system shall be sized in accordance with this section. Exception: Means of egress complying with Section (IFC [B] ) Cumulative occupant loads. Where the path of egress travel includes intervening rooms, areas or spaces, cumulative occupant loads the required capacity shall be determined in accordance with this section (IFC [B] ) Intervening spaces. Where occupants egress from one room, area or space through another, the design occupant load required capacity shall be based on the cumulative that portion of the occupant loads having required egress through adjacent of all rooms, areas or spaces added to the occupant load of the space under consideration to that point along the path of egress travel (IFC [B] ) Adjacent levels. The occupant load of a mezzanine or story with egress through a room, area or space on an adjacent level shall be added to the occupant load of that room, area or space. Where interior and exterior exit stairways or ramps serve more than one story, only the occupant load of each story considered individually shall be used in calculating the required capacity of such stairways or ramps serving that story. Where exit access stairways or ramps provide required access to an exit at an adjacent story, the required capacity of the adjacent story shall be based on that portion of the occupant load of the mezzanine or story having required egress through such adjacent story added to the occupant load of that story (IFC [B] ) Stairways. The capacity, in inches, of means of egress stairways shall be calculated by multiplying the occupant load served by such stairway by a means of egress capacity factor 2012 ICC FINAL ACTION AGENDA 1095

60 of 0.3 inches (7.62 mm) per occupant. Where stairways serve more than one story, only the occupant load of each story considered individually shall be used in calculating the required capacity of the stairways serving that story. Exception: For other than Group H and I-2 occupancies, the capacity, in inches, of means of egress stairways shall be calculated by multiplying the occupant load served by such stairway by a means of egress capacity factor of 0.2 inches ( 5.1 mm) per occupant in buildings equipped throughout with and automatic sprinkler system installed in accordance with Section or and an emergency voice/alarm communication system in accordance with Section (IFC [B] ) Continuity. The capacity of the means of egress required from any room, area, space, mezzanine or story of a building shall not be reduced along the path of egress travel until arrival at the public way (IFC [B] ) Exits or exit access doorways from spaces. Two exits or exit access doorways from any room, area or space shall be provided where one of the following conditions exists: 1. The occupant load of the space exceeds one of the values in Table When occupants egress through the space, that portion of the occupant load having required egress through such space to that point along the path of egress travel shall be added to the occupant load of the space under consideration. Exceptions: 1. In Group R-2 and R-3 occupancies, one means of egress is permitted within and from individual dwelling units with a maximum occupant load of 20 where the dwelling unit is equipped throughout with an automatic sprinkler system in accordance with Section or Care suites in Group I-2 occupancies complying with Section The common path of egress travel exceeds one of the limitations of Section Where required by Section , , , or Once established, the required number of exits or exit access doorways shall be maintained until arrival at the exit discharge or public way. Where a building contains mixed occupancies, each individual occupancy shall comply with the applicable requirements for that occupancy. Where applicable, cumulative occupant loads from adjacent occupancies shall be considered in accordance with the provisions of Section (IFC [B] ) General. Exits shall comply with Sections 1020 through 1026 and the applicable requirements of Sections 1003 through An exit shall not be used for any purpose that interferes with its function as a means of egress. Once a given level of exit protection is achieved, such level of protection shall not be reduced until arrival at the exit discharge. Within a building, once established, the required number of exits shall be maintained until arrival at the exit discharge or public way (IFC [B] ) Exits from stories. Two exits, or exit access stairways or ramps providing access to exits, from any story or occupied roof shall be provided where one of the following conditions exists: 1. The occupant load or number of dwelling units exceeds one of the values in Table (1) or (2). When exit access stairways or ramps provide required access to an exit at an adjacent story, the occupant load of the adjacent story shall be based on that portion of the occupant load of the mezzanine or story having required egress through such adjacent story added to the occupant load story under consideration. 2. The exit access travel distance exceeds that specified in Table (1) or (2) as 2012 ICC FINAL ACTION AGENDA 1096

61 determined in accordance with the provisions of Section Helistop landing areas located on buildings or structures shall be provided with two exits, or exit access stairways or ramps providing access to exits. Exceptions: 1. Rooms, areas and spaces complying with Section with exits that discharge directly to the exterior at the level of exit discharge, are permitted to have one exit. 2. Group R-3 occupancy buildings shall be permitted to have a one exit. 3. Parking garages where vehicles are mechanically parked shall be permitted to have one exit, 4. Air traffic control towers shall be provided with the minimum number of exits specified in Section Individual dwelling units in compliance with Section Group R-3 and R-4 congregate residences shall be permitted to have one exit. 7. Exits serving specific spaces or areas need not be accessed by the remainder of the story when all of the following are met: 7.1 The number of exits from the entire story complies with Table (1) or (2); 7.2 The access to exits from each individual space in the story complies with Section ; and 7.3 All spaces within each portion of a story shall have access to the minimum number of approved independent exits as specified in Table (1) or (2) based on the occupant load of that portion of the story. Reason: The 2012 Edition of the IBC is significant in that many fundamental Chapter 10 provisions have been clarified by modifying terminology or technical correlation. E10-09/10 and E22-09/10 were two such contributing proposals. Through those proposals, Sections 1004 and 1005 were altered to place means of egress occupant load determination and sizing provisions in functional context. When provisions are placed in proper technical context so as to gain consistency in interpretation and application, additional clarification is often required to complete the thought process and maximize understanding of the intent of the specific requirement. Proposed revisions are explained in numerical order. Presently, means of egress capacity continuity requirements are located in two sections, Section and Section does not contain a key requirement that the required capacity shall not be reduced until arrival at the public way. The two sections have been consolidated, clarified and located in technical context in Section Code users are not well served by having fundamental code requirements fragmented at two separate locations. Section 1005 is the logical location for this important means of egress sizing provision. This proposal places cumulative occupant load application requirements in the technical context of various means of egress design requirements such as required capacity and minimum numbers of exits or access to exits. Relocation of the cumulative occupant load provisions from Section inadvertently removes the spatial charging language of rooms, areas or spaces from Section Therefore, these terms are replaced in technical context in the next section, Section , and technical continuity is maintained. Section now contains provisions for how cumulative occupants loads are to be specifically applied in the determination of means of egress capacity requirements. Additionally, provisions have been clarified be consistent with current IBC means of egress capacity philosophy. For instance, 2012 Section (proposed Section ) implies that 100 percent of the occupant load of an adjacent level is to be added to the occupant load of a space under consideration at another building level. This proposal clarifies that only that portion of the occupant load having required egress through the adjacent level needs to be considered. Additionally, the last sentence of Section has been clarified and relocated in context in new Section It clarifies that cumulative occupant loads are not considered only when exit stairways (interior and exterior exit stairways) are employed in the design of the means of egress system. The current language states that any stairway, to include required exit access stairways, need not consider cumulative occupant loads. Historically, occupant loads from adjacent stories have not been considered when determining the required capacity for only exit components. As previously discussed, means of egress capacity continuity provisions have been consolidated and located in technical context in Section Cumulative occupant load provisions specifically applicable to the determination of the number of exits or exit access doorways from an individual room, area or space have been placed in context in Section Presently, the requirement that, cumulative occupant loads from adjacent occupancies shall be considered in accordance with the provisions of Section is located as an afterthought cross-reference as the last sentence of Section The actual requirement has been articulated and placed in technical context in the section. Additionally, currently there is no requirement to maintain the required number of exits or exit access doorways, once established, until arrival at the exit discharge or public way. This logical requirement will now be legally charged. Section has also been revised to include a legal requirement that the required number of exits be maintained within a building ICC FINAL ACTION AGENDA 1097

62 Section has been modified to include guidance as to what portion of the occupant loads of an adjacent story are to be applied in the determination of the number of exits required from a story above or below. Also, Exception 7 to Section has been deleted as there is currently no requirement for specific spaces to have access to all exits on a story. In summary, this proposal clarifies how cumulative occupant loads are to be applied in the determination of specific means of egress design requirements. The general provisions currently located in Section are replaced by more specifically applicable requirements located in context at Sections , and The provisions have also been clarified to indicate what portions of occupant loads from adjacent spaces are to be considered under the various design conditions. It should be noted that this proposal is consistent with current IBC means of egress design philosophy. Approval of this proposal will provide necessary guidance to designers and enforcement officials in these fundamental means of egress areas and will lead to more consistent interpretation and application of these important provisions. Through improved formatting and language this proposal further clarifies 2012 IBC means of egress provisions and increases functionality and technical continuity in this important area of life safety. Cost Impact: None E-Keith.doc Public Hearing Results Committee Action: Disapproved Committee Reason: Section would require exits to be sized on the first floor for the occupants for both the 1 st and 2 nd floor. This would be in conflict with the cascading stairway loading that has been utilized in the code for years. The language capacity shall not be diminished needs to stay in the code. E14, E15 and E17 should be worked on together.

Air traffic control towers shall be provided with the minimum number of exits specified in Section Individual dwelling units in compliance with Section Group R-3 and R-4 congregate residences shall be permitted to have one exit. Commenter s Reason: Four code change submittals (E14-12 through E17-12) were intended to address the issue of proper determination of cumulative occupant loads. The committee seemed to agree that there was confusion; however, did not agree on the appropriate remedy. This is a very subtle issue that impacts format, location and technical context. Currently, cumulative occupant load determination provisions are located in Section 1004, Occupant Loads. By providing general cumulative occupant load determination requirements in Section , there is the inference that cumulative occupant loads are applied uniformly for all means of egress design requirements. Such is not necessarily the case. Means of egress design requirements are intended to accomplish two goals: To maintain occupant tenability (i.e. exit access travel distance and intervening space provisions) and to adequately size and apportion the applicable means of egress components (i.e. capacity, numbers and configuration provisions). Occupant loads have virtually nothing to do with occupant tenability issues. On the other hand, capacity and numbers of exits/access to exits requirements are primarily occupant load driven. Capacity or sizing is the primary concern. The means of egress system must be appropriately sized to accommodate all occupants or combinations of occupants that could potentially use a given means of egress component. Accordingly, capacity provisions should be very liberally applied to all building designs. Numbers of exits/access to exits provisions are intended to complement capacity requirements by providing necessary opportunity/availability to reasonably egress the space, story or building should a fire event block a portion of the means of egress system. While capacity provisions are critical to occupant accommodation, numbers provisions beyond two have a point of diminishing return when considering cumulative occupant loads, especially where adjacent building levels are concerned. This proposal describes the application of cumulative occupant loads in the context of the specific design requirement. Sections and generally require that capacity will be based on that portion of cumulative occupant loads that egress through a given space or story. Section , Item 1, Exception 1 notes that foyers, lobbies, etc. need not have increased numbers of exits based on cumulative occupant loads. Please note that the capacity of the lobby exit is based on cumulative occupant loads. Section states that numbers of exits from a given story need not include contributing occupant loads from adjacent stories unless there are no other exits from an adjacent mezzanine. Again, bearing in mind that the required capacity from the exit level story would be based on applicable cumulative occupant loads, it is not necessary to consider cumulative occupant loads when determining the number of exits from a given story because of availability and opportunity. For a given story, there is no need to potentially increase the number of exits below for two reasons. If the fire event is on the lower story, occupants above may egress at their level without entering the fire floor. If the fire is at the upper level, there is no need for additional exits at the story below because there is no fire jeopardizing any of the exits. Additionally, there is reduced competition for the exits at the lower level based on rate of travel considerations. The increased size (capacity) of the means of egress system at the level below also mitigates the need for additional exits at that level. This methodology is consistent with those remarks applicable to Section as stated in the 2012 IBC Code and Commentary, Vol. 1 that states: The egress requirements for mezzanines or second floors that use exit access stairways to move to the ground level are handled similar to those spaces with accessory areas addressed in Section , versus the requirements for exiting from multiple levels in That is, that portion of the mezzanine/second floor occupant load that travels through the floor below to the exit is to be added to the occupant load of the space on the floor below. The sizing and number of the egress components must reflect this combined occupant load. This does not apply to the means of egress from a mezzanine/second floor that does not require travel through another level (i.e., an interior exit stairway serving the mezzanine/second floor). The IBC needs to identify how to apply cumulative occupant load provisions for various means of egress design scenarios and articulate those provisions so that they are universally understood by all code practitioners. This proposal is consistent with E5-09/10 means of egress philosophy contained in the 2012 IBC: however, restores the so-called cascade effect design considerations contained in earlier editions of the IBC as well as legacy codes.

65 E , , , , (IFC [B] , , , , ) Proposed Change as Submitted Proponent: Dennis Richardson, PE; Building Official, City of Salinas, representing Tri-Chapter (Peninsula, East Bay and Monterey Bay Chapters of ICC) Revise as follows: (IFC ) Cumulative occupant loads. Where the path of egress travel includes intervening rooms, areas or spaces, cumulative occupant loads shall be determined in accordance with this section (IFC [B] ) Intervening spaces. Where occupants egress from one room, area or space through another others, the design occupant load shall be assigned individually for each area and considered as required by Section be based on the cumulative occupant loads of all rooms, areas or spaces to that point along the path of egress travel (IFC [B] ) Adjacent levels for mezzanines. The occupant load of a mezzanine or story with all required egress through a room, area or space on an adjacent level shall be added to the occupant load of that room, area or space. Where a mezzanine is served by a means of egress, independent of the room or space in which it is located, the portion of occupant load accumulated to the room or space shall be added to the occupant load of that room or space. Exceptions: 1. Where a mezzanine is not required to be open in accordance with Exception 2 of Section , provided the loss of all exit access, through the room or space the mezzanine is located in, shall not reduce the available capacity from the mezzanine to less than 50% of the required egress capacity from the mezzanine. 2. Where a mezzanine is not required to be open in accordance with Exception 5 of Section (IFC [B] ) Adjacent stories. The portion of the occupant load accumulated from a story with exit access through an adjacent story shall be added to the story where access to an exit along that path is provided. Exceptions: 1. In occupancies other than Group H and I, provided the loss of all exit access through the adjacent story shall not reduce the available egress capacity from the story under consideration to less than 50 percent of its required egress capacity. 2. In occupancies other than Group H and I, where unenclosed exit access stairways serving only the first and second stories of a building equipped throughout with an automatic sprinkler system in accordance with Section , provided at least two means of egress are provided from both floors (IFC [B] ) Egress through intervening spaces. Egress through intervening spaces shall comply with this section. The capacity and minimum number of exits or exit access doorways and paths 2012 ICC FINAL ACTION AGENDA 1101

66 required from all interconnected portions of the exit access on a given story shall be considered individually for each room and in the aggregate for each portion of the exit access. The capacity and minimum number of exits or exit access doorways shall be provided based on the requirements in Sections 1005 and 1015, Egress capacity along any path of egress shall be based on the portion of the occupant loads from rooms, areas or spaces accumulated along that egress path. 1. Egress from a room or space shall not pass through adjoining or intervening rooms or areas, except where such adjoining rooms or areas and the area served are accessory to one or the other, are not a Group H occupancy and provide a discernible path of egress travel to an exit. Exception: Means of egress are not prohibited through adjoining or intervening rooms or spaces in a Group H, S or F occupancy when the adjoining or intervening rooms or spaces are the same or a lesser hazard occupancy group. 2. An exit access shall not pass through a room that can be locked to prevent egress. 3. Means of egress from dwelling units or sleeping areas shall not lead through other sleeping areas, toilet rooms or bathrooms. 4. Egress shall not pass through kitchens, storage rooms, closets or spaces used for similar purposes. Exceptions: 1. Means of egress are not prohibited through a kitchen area serving adjoining rooms constituting part of the same dwelling unit or sleeping unit. 2. Means of egress are not prohibited through stockrooms in Group M occupancies when all of the following are met: 2.1 The stock is of the same hazard classification as that found in the main retail area; 2.2 Not more than 50 percent of the exit access is through the stockroom; 2.3 The stockroom is not subject to locking from the egress side; and 2.4 There is a demarcated, minimum 44-inch-wide (1118 mm) aisle defined by full- or partial-height fixed walls or similar construction that will maintain the required width and lead directly from the retail area to the exit without obstructions. Reason: A number of code changes over the past two code cycles have, when combined together, made the code more restrictive as written or interpreted even though as advertised the individual code changes were not intended to increase the cost of construction. The issue primarily revolves around the assignment or accumulation of occupant load from one location to another and whether or not all, or none, or a portion of the occupant load from one area obtaining access to required exits through another story or area is added to the occupant load of that story or area for determination of the number of exits or exit access doorways and egress width. This code change addresses two areas of concern that the committee may wish to consider separately: Egress on a given level and egress from one story or level through another by way or unenclosed exit access stairways. In summary on a given level: This code change reinforces the concept that the occupant load is assigned to each occupied area individually. When there are intervening rooms, each area must be considered both individually and in the aggregate with other portions of the exit access to determine the number and width of exit access. Portions of the occupant load are accumulated along egress paths to determine the capacity of individual egress elements along those paths. But once occupants from one area make a choice and head out along one of several independent paths of egress travel, their occupant load is not added to some other area to determine how many paths of travel would be required from that different area as if a second fire were to occur at the same time in that area. Example D is provided at the end of this reason statement. In summary on separate levels: This code change also attempts to treat egress design along unenclosed exit access stairways through adjacent stories or through adjacent levels (in the case of mezzanines) in a similar manner recognizing previous limited instances where open exit access stairways from stories were considered as exits and the capacity (width) was required to be maintained but the occupant load was not added to the adjacent story providing exit access. Example A is provided in this reason statement. This code change also recognizes mezzanines with independent egress can function similar to a story in a building. Example B is provided in this reason statement. This code change recognizes mezzanines with sole egress through a room or area should have the occupant load added to that room or area. Example C is provided in this reason statement. In order to treat open exit access stairways, for both adjacent stories and levels (mezzanines), equally there must be some limitation on the loss of provided egress capacity from a mezzanine or story that gains a portion of its egress capacity through adjacent levels ICC FINAL ACTION AGENDA 1102

67 Except for the limited previous exceptions of occupancies other than H or I on the first or second floor equipped with sprinklers throughout (Example E), this code change places a limit of the loss of egress capacity through adjacent levels to no more than 50% of the required capacity. In the event more than 50% of required egress capacity would be blocked if egress through the adjacent level is lost then this code change requires the portion of occupant load to be added to the story or level where exit access is provided. This is consistent with the concept found in 2012 IBC section and is necessary in the case where two of three means of egress from a mezzanine could be open or two of four means of egress from a story could have open exit access through a story (both cases with more than 50% of the required capacity unprotected through the adjacent level or story). Description of Examples A, B and C: All three examples are a 10 story office building with a parking garage at the first two floors. Upper floors are cut away to help with view. All doors shown are 3-0 x 6-8 with 32 net clear. Typical design of each floor of the office building is for 850 occupants. Building is equipped throughout with a sprinkler system per Section (NFPA 13). Each floor requires 3 exits or exit access stairways in accordance with Section A minimum of two interior or exterior exit stairways are required from each story above the second floor per Section Total required net exit door width from each typical story = 850 x.15 = inches < 128 inches provided, OK. Loss of any one exit at interior exit stairway 1 results in no more than 50% of required capacity; Distribution of egress capacity OK per Section Example A: An two story open office suite covers the entire 3rd and 4th floors is and has a portion of the floor cut away. Access to interior exit stairway 1 is provided from the 4th floor using unenclosed exit access stairway 1. The occupant load of the 3rd floor is 850 without considering any occupant load from the adjacent floor. Occupant load of the partially cut away 4th floor is now 600. The portion of occupant load going to interior exit access stair way = x 32/.15 = 174. Required width of exit access stair 1 = 174 x.20 = 34.6 inches therefore use 44 inch minimum exit access stair per Section What occupant load is the third floor designed for? Are the typical floor exit doors and number of interior exit stairs code compliant? If the portion of occupant load from the 4th floor utilizing the unenclosed exit access stair is added to the third floor occupant load (or all of the occupant load depending how the current code is interpreted), the third floor will now be over 1000 occupant load and 4 means of egress will be required from the third floor down through the building even though the occupant load for the overall building is reduced and previous codes would have allowed this condition in occupancies other than H and I. This code change, for a B occupancy, would require the portion of the occupant load from the 4th floor to be added to the 3rd floor only if the exit access capacity required from the 4th floor would be reduced to less than 50% of required capacity if the exit access through the adjacent 3rd floor was blocked. In this example the egress would be ok as drawn. For H or I occupancies the portion of occupant load accumulated along the exit access stairway would be added to the occupant load of the story below as a requirement after this code change. Example B: In this example the third floor does not communicate with any other floor but a mezzanine with an occupant load of 350 is installed. The mezzanine is served by an independent exit going into interior exit stairway 3 and by exit access stairway 1 providing access to the 3rd floor. The occupant load of the 3rd floor is 850 without considering any occupant load from the mezzanine. What occupant load is the third floor designed for? Are the typical floor exit doors and number of interior exit stairs code compliant? According to the current code all or a portion of the occupant load from the mezzanine (depending on how it is interpreted) would need to be added to the 3rd floor and in either case, even though the mezzanine has direct access to an exit the building would now require 4 means of egress from the 3rd floor down. This code change for a B occupancy as shown, would require the portion of the occupant load from the third floor mezzanine to be added to the 3rd floor only if the exit access capacity required from the mezzanine would be reduced to less than 50% of required capacity if the exit access through the 3rd floor was blocked. For H or I occupancies the portions of occupant load accumulated along the exit access stairway would be added to the occupant load of the story below as a requirement of this code change. For the B occupancy, egress would be ok as shown in the example. Example C: In this example the third floor does not communicate with any other floor but a mezzanine with an occupant load of 350 is installed and the sole egress from the mezzanine is by two exit access stairways to the 3rd floor. The occupant load of the 3rd floor is 850 without considering any occupant load from the mezzanine. What occupant load is the third floor designed for? Are the typical floor exit doors and number of interior exit stairs code compliant? This example would be treated as required by current code where all of the occupant load from the mezzanine is added to the occupant load of the 3rd floor open office below. 3rd floor would now require 4 exits as the occupant load from the third story including the mezzanine would be greater than Example D: In this example, the occupant loads assigned to each room or area based on 2012 IBC section and the function of the space. All door hardware is either panic or classroom hardware and in all cases is openable in the direction of door swing without the use of a key or special knowledge or effort. All door hardware can be locked with a key in the direction opposite of door swing for security purposes of individual areas. For this example each door is a single leaf from 36 inch minimum up to 48 inch maximum and the building is equipped throughout with an NFPA 13 sprinkler system. If additional door width is required at a door location, based on capacity, two 36 doors are provided. In layout D.1, all rooms have adequate means of egress for the occupant load contained in the room when evaluated on an individual basis. The occupant load of the entire story is 700 and the story has an adequate number of exits when looked at in the aggregate (doors 3.1, 5.1 and 7.1). When the Accounting Office and General Office are looked at in the aggregate, they have adequate egress for an aggregate occupant load of 400 for this portion of the exit access (doors 5.1 and 6.1 which both must be have capacity for 200 occupants). The lobby has a total of 20 occupant load and door 7.1 must be sized for an accumulated occupant load along this egress path of 360 (200 from door 6.1, 140 from door 4.1 and 20 from the lobby). Utilizing the concept of one fire, if there was a fire in the lobby then all occupants would have adequate access to other means of egress through doors 5.1 and 3.1. If the fire occurred when doors 4.1 and 6.1 are locked from the lobby side then the limited number of occupants in the lobby have access to adequate egress through door ICC FINAL ACTION AGENDA 1103

68 If the fire occurs in another room, the general office for example, the portion of occupant load from the general office and the sales office with egress through the lobby are not added to the occupant load of the lobby to determine the number of exits or exit access doors from the lobby but the occupant load is accumulated along this path to determine the required capacity of doors 7.1 along this path. Because those individuals from other rooms, if exiting from a fire through the lobby, would have already exercised their option of two means of egress from the room where the occupants originated and there is no need to add the occupants or the portion of the design occupant load through the lobby to the occupant load of the lobby to determine the number of means of egress from the lobby. The code does not assume both a fire that persons are exiting from and then encountering another different fire along the way. Egress in layout D.1 would meet the code as revised by the proposed change. In layout D.2, all rooms have adequate means of egress for the occupant load contained in the room when evaluated on an individual basis. The occupant load of the entire story is still 700 and the story has an adequate number of exits when looked at in the aggregate (doors 3.2, 5.2 and 7.2). Since the sales office also has required egress through the general office, the accounting office, general office and sales office must be looked at in the aggregate and based on the total aggregate occupant load of 680 for this portion of the exit access. Three exit or exit access doors are required and provided from this portion of the exit access (door 3.2, 5.2, and 6.2). The capacity of door 5.2 and 6.2 must be designed based on an accumulated occupant load 270 along each egress path which is determined as follows: (140, the portion from the sales office, plus 100 from the accounting office, and 300 from the general office) all divided by 2= 270. The capacity of door 7.2 is determined based on the occupant load of 270 used to determine the occupant load of door 6.2 along with the accumulated occupant load of 20 from the lobby for a total occupant load of290 for the capacity of door 7.2 along the continuation of this egress path. This is consistent with Figure of the 1012 IBC Commentary and its accompanying explanation. Egress in layout D.2 would meet the code as revised by the proposed change. This example has adequate egress from each room, story and portion of the exit access when considered in the aggregate but it would not comply with the 2009 IBC because all occupants do not have access to all required exits from the story as was required by 2009 IBC section This was resolved by E5 and E120 in the past code cycle. This example would also not comply with the literal read of the 2012 IBC because all of the occupant load from the sales office and the accounting office would be added to the general office for a total of 680 requiring three means of egress from the general office. Example E: This example illustrates an egress system allowed for occupancies other than H and I in the first two floors of a building equipped throughout with an NFPA 13 sprinkler system. This arrangement was allowed under the 2006 IBC section , exception 9 without adding the occupant load to the floor below. This code change would continue to allow this configuration as long as the capacity from each floor is maintained as required by the code. This configuration would apparently not meet the current code as the occupant load or a portion of the occupant load from the second floor would currently be required to be added to the occupant load of the first floor causing the occupant load to have three exits. This was apparently an unintended consequence of E122 06/07. In Conclusion: This code change would clarify egress from a single level through intervening rooms would have occupant load assigned to each room and be evaluated both individually and in the aggregate for each portion of the exit access. This code change would still require occupant load from an adjacent story or level to be added to an adjacent level when the sole egress occurs through the story. This code change provides a framework utilizing existing exceptions for the egress through an adjacent story or level to be considered in a similar manner depending on the degree of independent egress from the story or mezzanine ICC FINAL ACTION AGENDA 1104

71 Cost Impact: This change will not increase the cost of construction. Staff Note: The version of E15-12 shown above was part of the errata posted on the ICC website and also appeared in the Report of Hearings. Public Hearing Results Committee Action: Disapproved Committee Reason: The proposal seems to treat the 2 nd floor like a mezzanine regardless of how close the exit access stairways are to the exterior exits in the level of exit discharge. This would be in conflict with the cascading stairway loading that has been utilized in the code for years. Loss of exit access is to open for interpretation. The proposed language is very confusing. The intent is not clearly expressed. Disapproval is also consistent with the committee vote on E17. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Dennis Richardson, PE; Building Official, City of Salinas, representing Tri-Chapter (Peninsula, East Bay and Monterey Bay Chapters of ICC), requests Approval as Modified by this Public Comment Replace the proposal with the following: Cumulative occupant loads. Where the path of egress travel includes intervening rooms, areas or spaces, cumulative occupant loads shall be determined in accordance with this section (IFC [B] ) Intervening spaces or accessory areas. Where occupants egress from one or more room, area or space through another others, the design occupant load shall be the combined occupant load of interconnected accessory or 2012 ICC FINAL ACTION AGENDA 1107

72 intervening spaces. Design of egress path capacity shall be based on the cumulative portion of occupant loads of all rooms, areas or spaces to that point along the path of egress travel (IFC [B] ) Adjacent levels for mezzanines. That portion of the occupant load of a mezzanine or story with required egress through a room, area or space on an adjacent level shall be added to the occupant load of that room, area or space (IFC [B] ) Adjacent stories. Other than for the egress components designed for convergence in accordance with Section , the occupant load from separate stories shall not be added. Commenter s Reason: Over the past two code cycles there have been numerous changes to the egress provisions. Along the way a number of basic premises of the code have been slightly modified with the result of inconsistent interpretation and application of the code. The goal of this code change is to state how occupant load is addressed in one place (Section 1004) so that the user can consistently apply the occupant load in other sections utilized to calculate the width (or capacity) and determine the number of exits or exit access paths. During the past two code cycles seemingly straight forward changes have had the effect of making the code more restrictive through interpretation even though they were not advertised as such Intervening spaces: The current code as written gives inconsistent interpretations as shown in the 2012 ICC Code and Commentary Figure on page and Figure (1) on page In Figure , if interpreted literally as written, a small lobby with 10 occupant load with one path of exit travel through it would either have all or part of the occupant load from the next room added to it to determine both number and capacity of exits. If the code is applied literally in this example, then the design occupant load (now much larger) would require two exits or exit access from the lobby on its own even though the large room driving egress already has access to two exits. In the example accompanying Figure (1) part of the occupant load is added to the corridor to determine the corridor now needs three exits which is incorrect as the room driving this condition already had access to three exits or exit access and the overall story only needs three exits. Instead of taking occupant load from one space and adding it to another as implied by the current code for the overall design occupant load, this public comment emphasizes rooms that share an egress path must be looked at for the occupant load in the aggregate to address number of exits, door swing, hardware, etc. and each path of egress travel width (or capacity) must be designed for an accumulation of the portion of occupant load with egress along that path. Each individual room must also have access to the required egress as currently required by code Mezzanines: Egress from mezzanines has been treated differently than stories in the IBC code for a number of years. The concept provided here is only the portion of occupant load with required egress through the room, area or space shall be added to the occupant load of the room, area or space below. This accounts for mezzanines where there is considerable independent egress directly off of the mezzanine and also for the conditions where some or all of the required egress from the mezzanine is through the level below Stories: Historically in the IBC occupant load has not needed to be accumulated through exits from one story to another as long as both the maximum number and capacity at any story is maintained in the stories below. This has been referred to the cascading stairway loading effect. The concern of conflict with the cascading stairway loading utilized by the code for years was mentioned by the egress committee in the disapproval of E14, E15 and E17. In past codes, there is one instance where occupant load is added between stories when there is convergence with egress to a central level occurring at the same time from both above and below. This is acknowledged in this public comment. The loss of the cascading loading for stairways may have occurred, in the minds of some, when unenclosed exit stairways found in section 1020, exceptions 8 and 9, of the 2006 IBC were relocated by E122-06/07 from the exit provisions to the exit access provisions. E122-06/07 stated it did not increase the cost of construction and there was no discussion in the E122-06/07 reason of any effect on cascading stairway loading at that time. Yet by renaming unenclosed exit stairs as unenclosed exit access stairs some practitioners interpreted this as a need to now add the portion of occupant load from an exit access stairway to the story below (as part of the exit access) instead of maintaining both the capacity and number of means of egress from the story as has historically been done for exits. This cascade stairway loading concept was alive and well regarding egress width from a story in section of the 2006 IBC, again in the last sentence of section of the 2006 IBC, and finally addressed for the number of exits from a story in 2006 IBC section The last section of this public comment attempts to address this issue to ensure, even though egress through an adjacent story has been reorganized, the intent of maintaining the cascade stairway loading is maintained as pointed out by the egress committee. E15-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1108

73 E , , (IFC [B] , , ) Proposed Change as Submitted Proponent: Charles S. Bajnai, Chesterfield County, VA, ICC Building Code Action Committee Revise as follows: (IFC [B] ) Adjacent levels. That portion of the occupant load of a mezzanine or story with required egress through a room, area or space on an adjacent story level shall be added to the occupant load of that room, area or space (IFC [B] ) Stairways. The capacity, in inches, of means of egress stairways shall be calculated by multiplying the occupant load served by such stairway by a means of egress capacity factor of 0.3 inches (7.62 mm) per occupant. Where interior or exterior exit stairways serve more than one story, only the occupant load of each story considered individually shall be used in calculating the required capacity of the stairways serving that story. Where exit access stairways provide required access to an exit at an adjacent story, the occupant load determined in accordance with Section shall be used in calculating the required capacity of the means of egress serving that story. Exception: For other than Group H and I-2 occupancies, the capacity, in inches (mm), of means of egress stairways shall be calculated by multiplying the occupant load served by such stairway by a means of egress capacity factor of 0.2 inch (5.1 mm) per occupant in buildings equipped throughout with an automatic sprinkler system installed in accordance with Section or and an emergency voice/alarm communication system in accordance with Section (IFC [B] ) Other egress components. The capacity, in inches (mm), of means of egress components other than stairways shall be calculated by multiplying the occupant load served by such component by a means of egress capacity factor of 0.2 inch (5.1 mm) per occupant. Where exit access ramps provide required access to an exit at an adjacent story, the occupant load determined in accordance with Section shall be used in calculating the required capacity of the means of egress serving that story. Exception: For other than Group H and I-2 occupancies, the capacity, in inches (mm), of means of egress components other than stairways shall be calculated by multiplying the occupant load served by such component by a means of egress capacity factor of 0.15 inch (3.8 mm) per occupant in buildings equipped throughout with an automatic sprinkler system installed in accordance with Section or and an emergency voice/alarm communication system in accordance with Section Reason: This proposal is submitted by the ICC Building Code Action Committee (BCAC) The BCAC was established by the ICC Board of Directors to pursue opportunities to improve and enhance an assigned International Code or portion thereof. This includes both the technical aspects of the codes as well as the code content in terms of scope and application of referenced standards. Since its inception in July, 2011, the BCAC has held 3 open meetings and over 15 workgroup calls which included members of the BCAC as well as any interested party to discuss and debate the proposed changes. Related documentation and reports are posted on the BCAC website at: The 2012 Edition of the IBC has formalized the concept of accessing exits from adjacent stories. Accordingly, several means of egress design details need to be clarified so as to be consistent with the intent of Section Currently, Section literally requires that (100% of) the occupant load of a mezzanine or story with egress through a room, area or space on an adjacent level shall be added to the occupant load of that room, area or space. That would be appropriate if there were no other exits serving the mezzanine or story. However, if the mezzanine or story also has other independent exits that do not egress through the adjacent story, it is reasonable to assume these other independent exits can and will be used by the occupants of that mezzanine or story. This proposal clarifies that only that portion of the occupant load of the level of origin actually using exit access stairways need be used in determining means of egress requirements for the adjacent story. To be consistent with this philosophy, Section has also been modified to state an identical provision for exit access ramps which provide required access to an exit at an adjacent story ICC FINAL ACTION AGENDA 1109

74 Additionally, Section has been modified to clarify that only the occupant load of a story directly accessing an interior exit stairway need be considered in determining the required capacity of such interior exit stairway that serves additional stories. The cascade effect is accounted for in the means of egress capacity factor for stairways in Section A cross-reference to the method for determining the required capacity for areas served by exit access stairways from an adjacent level has also been provided. Section (Mezzanine levels) of the 2009 IBC reads very similarly to Section (Adjacent levels) of the 2012 IBC. The 2009 IBC Commentary states, The egress requirements for mezzanines are handled similar to those addressed in Section with accessory areas versus the requirements for exiting from multiple levels in Section That is, that portion of the mezzanine occupant load that discharges to the floor below is to be added to the occupant load of the space on the floor below. The sizing and number of the egress components must reflect this combined occupant load. This does not apply to the means of egress from a mezzanine that does not require travel through another level (i.e., an exit stairway serving the mezzanine). Clarification is achieved by adding the that portion language in the commentary to the actual provision. Approval of this proposal is consistent with the means of egress philosophy contained in the 2012 IBC and will result in the more consistent interpretation and application of fundamental means of egress design provisions. Cost Impact: This code change proposal will not increase the cost of construction E-BAJNAI-BCAC.docx Public Hearing Results Committee Action: Disapproved Committee Reason: The term portion of the occupant load is too open for interpretation and is confusing. Elimination of the enclosures for the stairways does not change how the occupants move to egress from the space. This would be in conflict with the cascading stairway loading that has been utilized in the code for years. This would have significant effect on the size and number of exits in a two story building with two exit access stairways. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Charles S. Bajnai, Chesterfield County, VA, ICC Building Code Action Committee, requests Approval as Modified by this Public Comment Replace the proposal with the following: (IFC [B] ) Adjacent levels. That portion of the occupant load of a mezzanine or story with required egress through a room, area or space on an adjacent story level shall be added to the occupant load of that room, area or space. Commenter s Reason: This public comment is submitted by the ICC Building Code Action Committee (BCAC). The BCAC was established by the ICC Board of Directors to pursue opportunities to improve and enhance an assigned International Code or portion thereof. This includes both the technical aspects of the codes as well as the code content in terms of scope and application of referenced standards. Since its inception in July, 2011, the BCAC has held 5 open meetings and numerous workgroup calls which included members of the BCAC as well as any interested party to discuss and debate the proposed changes and the public comments. Related documentation and reports are posted on the BCAC website at: Revision to the code text is made to clarify the Code s intent and be consistent with the 2012 IBC Commentary under Section The 2012 IBC Commentary under Section states: The egress requirements for mezzanines or second floors that use exit access stairways to move to the ground level are handled similar to those spaces with accessory areas addressed in Section , versus the requirements for exiting from multiple levels in That is, that portion of the mezzanine/second floor occupant load that travels through the floor below to the exit is to be added to the occupant load of the space on the floor below. The sizing and number of the egress components must reflect this combined occupant load. This does not apply to the means of egress from a mezzanine/second floor that does not require travel through another level (i.e., an interior exit stairway serving the mezzanine/second floor).

75 E18-12 Table (IFC [B] Table ) Proposed Change as Submitted Proponent: Al Godwin, CBO, CPM, Aon Fire Protection Engineering representing Aon Fire Protection Engineering Revise as follows: TABLE (IFC [B] TABLE ) MAXIMUM FLOOR AREA ALLOWANCES PER OCCUPANCY FUNCTION OF SPACE OCCUPANCY LOAD FACTOR Mercantile Areas on other floors Basement and grade floor areas 60 gross 30 gross Primary floors of the retail space b Floors and mezzanine other than the primary floors Storage, stock, shipping areas 30 gross 60 gross 300 gross (Portions of table and notes not shown remain unchanged.) b. The primary floor is the entry floor of the retail space. More than one floor will be considered a primary floor where customer entry from outside the retail space can occur on different levels. Other floors are secondary floors, mezzanines, and basements that customers can only access once inside the retail space. Reason: It has never been made clear if the grade floor is the 1 st floor of the retail space, or only those floors at grade. What about retails spaces that are on the 2 nd floor of a strip center or mall? Is it assumed that they will not be as crowded as a retail space on the 1 st floor? What if there are two grade floors? Why does a basement level have the same occupant load as the grade floor. This revision is provided to hopefully clarify the requirement. At least provide better clarification in the commentary. Cost Impact: This code change proposal will not increase the cost of construction. Staff Note: The original proposal had an errata in the 2 nd column in the struck-out language. The proposal as shown has been corrected. T E-Godwin.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The issue is more the occupant load of the space rather than if this is the entry floor or not. A store could have a primary retail space on more than one floor This proposal would not work for malls. Primary floor would not have consistent interpretation. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1111

76 Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment 1: Al Godwin, CBO, CPM, Aon Fire Protection Engineering representing Aon Fire Protection Engineering, requests Approval as Submitted Commenter s Reason: When published in the monograph the 60 gross and 30 gross of the existing struck through language were transposed. This added confusion to the proposal. The Committee stated that the issue is not what floor they are on but the occupant load of the space. However, the current code already assumes that the grade floor and basement floor will have the largest occupant load regardless of what products are present on these or other floors that might attract customers. This proposal is only to clarify that the grade floor of a retail space is the entry floor of the retail space. Thus, a retail space whose entry floor is on the second level would use the 30 factor and not the 60 factor. Also included is direction that in some buildings like malls, 2 story retails spaces may have two grade or entry floors. Public Comment 2: Stephen Thomas, Colorado Code Consulting, LLC representing Colorado Chapter ICC, requests Approval as Modified by this Public Comment Replace the proposal with the following: TABLE (IFC [B] TABLE ) MAXIMUM FLOOR AREA ALLOWANCES PER OCCUPANCY FUNCTION OF SPACE OCCUPANT LOAD FACTOR a Mercantile 60 gross Areas on other floors 60 gross Basement and grade floor areas 30 gross Storage, stock, shipping areas 300 gross (Portions of table and notes not shown remain unchanged.) Commenter s Reason: The original proposal tried to define what the primary floor was for mercantile occupancies. This public comments attempts to make this requirement easier for the code user. The different occupant load factors for various floors were originally based on multi-story single operator buildings. However, the use of these buildings is no longer the same as they were. Many of the big box retailers are now constructing multi-story buildings. We do not believe the number of occupants will be any different on different floors. Therefore, we are recommending that a single occupant load factor be used for all floors. 60 square feet per occupant was selected because it is a more reasonable number in today s retail environment. Much of the floor area is covered with display cases and counters. The actual number of people, even at Christmas time or Black Friday, would not exceed the 60 square feet limit. This occupant load factor is more reasonable and still provides the required number and capacity of exits from the building. E18-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1112

77 E (IFC [B] ) Proposed Change as Submitted Proponent: Al Godwin, CBO, CPM, Aon Fire Protection Engineering representing Aon Fire Protection Engineering Revise as follows: (IFC [B] ) Increased occupant load. The occupant load permitted in any building, or portion thereof, is permitted to be increased where approved by the building official from that number established for the occupancies in Table , provided that all other requirements of this the code or any other applicable codes are also met based on such modified number and the occupant load does not exceed one occupant per 7 square feet (0.65 m 2 ) of net occupiable floor space. In making the decision, the building official shall be permitted to consider such issues as: 1. Is this a temporary or permanent increase; 2. The function and operation of the business; 3. Openness of egress flow; 4. Management control of crowd and evacuation issues; 5. The effect of seating or tables on the egress path; 6. Is alcohol present. After review, the building official shall be permitted to require a lesser density. Where required by the building official, an approved aisle, seating or fixed equipment diagram substantiating any increase in occupant load shall be submitted. Where required by the building official, such diagram shall be posted. Reason: As written, the 1:7 seems automatic if extra exits and width are provided. Some designers have felt that it is automatic and expressed opposition when other factors were brought into the evaluation. However, there are many issues that should be considered in evaluating the increase. Only a few are listed. There is a difference in increasing the occupant load for rooms used for code hearings than rooms used as a night club, with low lights and patrons consuming alcohol. To allow an occupant load increase requires a different evaluation. Also, there are other codes that are affected as well. An occupant load increase may change the alarm specifications, the restroom requirements, the fresh air requirements, etc. All of these factors are part of the evaluation. Cost Impact: This code proposal will not increase the cost of construction since no extra construction costs are involved E-Godwin.doc Public Hearing Results Committee Action: Disapproved Committee Reason: To design a space for an increased occupant load the designer is already exceeding minimum code requirements and there is already a maximum number permitted. The proposed language is too subjective. The intent is already addressed in the codes, therefore the proposed language is largely duplicative. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1113

78 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Al Godwin, CBO, CPM, representing Aon Fire Protection Engineering Corporation, requests Approval as Modified by this Public Comment. Replace the proposal with the following: Increased occupant load. The occupant load permitted in any building, or portion thereof, is permitted to be increased, where approved by the building official, from that number established for the occupancies in Table , provided that all other requirements of the code are also met based on such modified number and the occupant load does not exceed one occupant per 7 square feet (0.65 m 2 ) of net occupiable floor space. Where required by the building official, an approved aisle, seating or fixed equipment diagram substantiating any increase in occupant load shall be submitted. Where required by the building official, such diagram shall be posted. Where required by the building official, an approved aisle, seating or fixed equipment diagram substantiating any increase in occupant load shall be submitted. Where required by the building official, such diagram shall be posted. Commenter s Reason: While all of the items listed in the original proposal and the reason statement are applicable, the Committee felt that these items will be addressed before an increase will be permitted. As such, the proposal was a duplicate of provisions that already exists. Therefore, the proposal has been reduced to just add when approved by the building official. As currently written, it is not clear if 7 square foot per person is a right that can be claimed anytime extra doors are present, or if the building official has some decision making authority. This will clarify that it is not a right but is subject to review. The commentary should identify that in making this decision, the building official should consider all of the items in the original proposal and those listed in the Reason statement.

79 E (New) [IFC [B] (New)] Proposed Change as Submitted Proponent: John Williams, CBO, Chair, ICC Ad Hoc Committee on Health Care Add new text as follows: (IFC [B] ) Occupancy sensors. Occupancy sensors shall be permitted to activate the required illumination for the means of egress provided they meet all of the following conditions: 1. The occupancy sensors operate as fail safe devices when the occupancy sensor fails; 2 Where the occupancy sensor is activated by an occupant the area served is illuminated for a minimum duration of 15 minutes; 3. The occupancy sensor operates as a fail safe device in the event of a power supply failure to the emergency lighting system required by Section The means of egress is not required to have illumination to charge luminous egress path markings in accordance with Section Reason: This change permits the use of occupancy sensors which has been allowed in some jurisdictions. It also helps reduce energy as mandated by DOE. There are several proposals from the Adhoc Health Care Committee dealing with Section The proposals can be accepted individually, however, the proposals can work together. This proposal is submitted by the ICC Ad Hoc Committee on Healthcare (AHC). The AHC was established by the ICC Board of Directors to evaluate and assess contemporary code issues relating to hospitals and ambulatory healthcare facilities. The AHC is composed of building code officials, fire code officials, hospital facility engineers, and state healthcare enforcement representatives. The goals of the committee are to ensure that the ICC family of codes appropriately addresses the fire and life safety concerns of a highly specialized and rapidly evolving healthcare delivery system. This process is part of a joint effort between ICC and the American Society for Healthcare Engineering (ASHE), a subsidiary of the American Hospital Association, to eliminate duplication and conflicts in healthcare regulation. Since its inception in April, 2011, the AHC has held 5 open meetings and over 80 workgroup calls which included members of the AHC as well as any interested party to discuss and debate the proposed changes. All meeting materials and reports are posted on the AHC website at: Cost Impact: None E-Williams-Adhoc.docx Public Hearing Results Committee Action: Disapproved Committee Reason: Allowance for automatic controls is needed as part of energy conservation and green building concerns. It is recognized that timers are used to turn on the lights to charge the photoluminescent stripes required in high-rises by Section However, there is a concern that there are currently no standards for testing or listing of these controls specifically looking for a fail-safe device. These automatic controls should be limited to general means of egress lighting and not relied on for emergency means of egress lighting. This disapproval is consistent with E22 and E24.

80 Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment 1: John Williams, Adhoc Health Care MOE study group, requests Approval as Modified by this Public Comment. Replace the proposal with the following: (IFC [B] ) Illumination required. The means of egress, including the exit discharge, shall be illuminated at all times the building space served by the means of egress is occupied. Exceptions: 1. Occupancies in Group U. 2. Aisle accessways in Group A. 3. Dwelling units and sleeping units in Groups R-1, R-2 and R Sleeping units of Group I occupancies. 5. Portions of the means of egress provided with automatic lighting controls installed in accordance with Section (IFC [B] ) Occupancy sensors Automatic lighting controls. Occupancy sensors Automatic lighting controls shall be permitted to activate the required illumination for the means of egress provided they meet all of the following conditions: 1. The controls shall be configured to provide the required illumination within each room or space while occupied. 2. Where provided, occupant sensors shall activate the required illumination the occupancy sensor is activated by an occupant the area served is illuminated for a minimum duration of 15 minutes Where the automatic lighting controls fail, the controls shall fail in the on or operating state. The occupancy sensors operate as fail safe devices when the occupancy sensor fails; 4. Occupant sensors shall not extinguish lighting The means of egress is not required to have illumination to charge luminous egress path markings in accordance with Section All designated emergency lighting luminaries in the means of egress path shall operate in the event of emergency system activation providing light levels in accordance with Section The occupancy sensor operates as a fail safe device in the event of a power supply failure to the emergency lighting system required by Section The automatic lighting controls shall be tested as a component of the emergency lighting equipment in accordance with the IFC Section Commenter s Reason: The revised proposal responded to the committee s comments. The testing section was added in Item 6. Item 5 refines how the emergency means of egress lighting if used. We refined other areas of the proposal to indicate the need to fail on and not interfere with any of the luminous marking system needs. Today s practice: Emergency fixture options Battery powered wall fixtures Battery back-up ceiling fixtures Designated fixtures connected to emergency panels Normal power ON OFF as standard feature May be turned OFF when Mostly ON 24/7 space unoccupied, maybe left ON depending on design Normal power OFF ON as standard feature ON as standard feature ON when transfer switch connects to emergency generator 2012 ICC FINAL ACTION AGENDA 1116

The rationale provided by the ICC Review committee substantiates that the proposal is acceptable for safe egress out of the building for almost 100% of the time, but is somehow not reliable for egress in a fire event. This logic does not make sense. The concern that there is no current standard to test the devices is not valid, as the industry will create a test upon acceptance. Hospitals are required to have illumination of means of egress and have invested a substantial amount of money into emergency generators, and emergency power distribution systems that have proven to be reliable in many situations. To require an additional luminous egress path markings is redundant. Hospitals already have normal power plus emergency power. The need for the markings is an expense that will add no more value to safe egress in the event of a fire. Healthcare depends on emergency power systems to support life safety functions such as surgery, emergency services and the like, so to not consider this emergency power as a reliable source for egress illumination defies logic. Healthcare costs are a major national concern. To increase construction costs with three required redundant systems is not good use of healthcare resources that should be allocated to the patient at the bedside. I am submitting this request on behalf of the Wisconsin Healthcare Engineers Association Codes & Standards committee representing over 700 members in the State of Wisconsin. Thank you for your time and consideration of my comments. E25-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1117

82 E (IFC [B] ) Proposed Change as Submitted Proponent: Gene Boecker, AIA, Code Consultants, Inc, representing self Revise as follows: (IFC [B] ) Accessible means of egress required. Accessible means of egress shall comply with this section. Accessible spaces shall be provided with not less than one accessible means of egress. Where more than one means of egress are required by Section or from any accessible space, each accessible portion of the space shall be served by not less than two accessible means of egress. Exceptions: 1. Accessible means of egress are not required in alterations to existing buildings. 2. One accessible means of egress is required from an accessible mezzanine level in accordance with Section , or In assembly areas with sloped or stepped aisles, one accessible means of egress is permitted where the common path of travel is accessible and meets the requirements in Section Accessible means of egress are not required from levels of parking garages that do not contain accessible parking spaces. Reason: According to Section and of the IBC, accessible parking is required on levels that have a direct connection to the building. Van accessible parking is allowed to be limited to the ground floor level. Hence accessible parking is not required on all levels of a parking garage. It is often unclear whether an accessible means of egress, once provided for the accessible parking spaces within a garage on a single level, should be applied throughout the structure. Because the intent for accessible means of egress is to provide access for individuals with mobility disabilities, this would not be necessary on parking garage levels without accessible parking spaces. Section of the IBC requires an elevator to serve as an accessible mean of egress in buildings where a required accessible floor is more than four stories above the level of exit discharge (a five story building). While accessible parking is not required on the upper levels of a garage (without access to the building on those levels) that does not mean that the upper levels are not to be designed for accessibility. It simply means that they are not required to be designed for mobility disabilities. The floors must still be designed for other types of disabilities. Protruding objects/headroom obstructions are still required to be addressed for visual disabilities and a telephone bank would need to provide units for the hearing impaired. Tactile exit signs are unaffected by this proposal because they are required under Section and are not a part of the accessible means of egress provisions in Section Similarly, although the code contains an exemption for areas of refuge for parking garages, a 48 inch clear width between handrails would still be required since an open parking garage is usually without sprinklers. The purpose of the 48 inch clear width is to facilitate fire fighter capability to carry a wheelchair down the stairs. If there is no accessible parking on the upper levels, this too should not be a requirement. While accessible parking may be provided on multiple levels because building entrances are provided at various levels, full compliance should not be necessary at levels where mobility accessibility is not an issue. If accessible parking is provided on all levels, then the accessible means of egress should be provided on all levels as well. However, if accessible parking is provided on only the grade level of an eight-level parking garage, the requirements for an accessible means of egress elevator should not apply and the stairways serving the upper levels should be designed based on required capacity rather than a blanket 48 inch between handrail requirement. Cost Impact: The code change proposal will reduce the cost of construction in some instances #2-E-Boecker.doc 2012 ICC FINAL ACTION AGENDA 1118

83 Public Hearing Results Committee Action: Disapproved Committee Reason: The allowance for no accessible means of egress on levels of parking garages that do not contain accessible parking spaces conflicts with the needs of persons with mobility impairments that are not using accessible parking spaces. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Gene Boecker, AIA, Code Consultants, Inc (CCI), requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Accessible means of egress required. Accessible means of egress shall comply with this section. Accessible spaces shall be provided with not less than one accessible means of egress. Where more than one means of egress are required by Section or from any accessible space, each accessible portion of the space shall be served by not less than two accessible means of egress. Exceptions: 1. Accessible means of egress are not required in alterations to existing buildings. 2. One accessible means of egress is required from an accessible mezzanine level in accordance with Section , or In assembly areas with sloped or stepped aisles, one accessible means of egress is permitted where the common path of travel is accessible and meets the requirements in Section Accessible means of egress are not required from levels of parking garages that do not contain accessible parking spaces. In parking garages, the second accessible means of egress shall be permitted to use the parking garage drive aisles. Commenter s Reason: The committee disapproved this based on the assumption that disabled people who choose not to park in the designated spaces need to have an accessible means of egress. Fundamentally, this argument is flawed. The code does not require all doors to act as exits - even if they lead to the outside - only those which are designated as exits. If other doors are provided, while occupants can use them if they so choose, the code does not obligate the designer to construct them as exits. Irrespective of the concerns expressed, this is a design issue that continues to come up in discussions and should have a resolution. If it is important that accessible means of egress be provided from all parts of a parking garage, regardless of whether or not there are marked spaces, then the code should require all spaces to be designed for Accessibility. It does not do so because it recognizes specific locations which must be set aside. Garages often have a configuration where the drive aisle slopes from one end of the garage to the other. At one end is a set of stairs. Diagonally opposite that is another set of stairs. An elevator may or may not be provided at one end. If an elevator is not present, then the second accessible means of egress is down the drive aisle to the far corner of the garage. The drive aisle is not required to be designed for accessibility. It usually has a slope of 10 percent rather than a maximum of 8.3 percent; and, the drive aisle does not have landings at 30 inch vertical increments or handrails on both sides. Hence it is not a ramp which is designed to meet accessibility needs. If an elevator is provided, the second accessible means of egress must be provided with emergency standby power. This is an added cost of $35,000 to $100,000 depending on geographic location and height of the garage. The proposed amendment accepts the premise that there may be persons with disabilities on levels other than those with designated spaces. However, it offers a suggestion that the drive aisle be used as the second accessible means of egress. One accessible means of egress can be the stairs near the side where the accessible spaces are provided. This stairway must be widened to 48 inches clear between handrails. According to the concerns expressed by the committee, this would need to be extended upward to the full height of the stair. While questionable relative to the code assumptions as stated in the first paragraph, this is a relatively small expense to the overall garage. The real concern is how to provide the second accessible means of egress. The sloped drive aisles create a limitation in design and the emergency standby power represents a significant increase is cost ICC FINAL ACTION AGENDA 1119

84 The proposal seeks a third alternative, still keeping with the concerns expressed by the committee. Because the path of egress in a garage is most often in descent, the sloped aisles, although greater than the slopes for accessible design, should be acceptable. The slope is in the same direction as gravity. Breaking is a concern but not overcoming the vertical change in elevation. Additionally, parking garages have a significant safety record for human life. This is a reasonable alternative to the interpretation that it is necessary to provide something for a part of the building where the need is not evident.

85 E , (IFC [B] , ) Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: (IFC [B] ) Stairways. In order to be considered part of an accessible means of egress, a stairway between stories shall have a clear width of 48 inches (1219 mm) minimum between handrails and shall either incorporate an area of refuge within an enlarged floor-level landing or shall be accessed from either an area of refuge complying with Section or a horizontal exit. Exit access stairways that connect levels in the same story are not permitted as part of an accessible means of egress. Exceptions: 1.

86 Reason: This proposal is for the most part editorial and makes the language in the exceptions consistent. There is with one new items added and one relocation for added clarity. Areas of refuge are not required at stairways/elevators in Group I-3 facilities is a new exception to coordinate with the DOJ 2010 ADA Standards for Accessible Design. The Department of Justice (ADA Exception 2) had concerns that areas of refuge could pose security risks in correctional facilities due to their enclosed nature, and a building designer has the option of locating a facility s accessible spaces such that an elevator need never be used as part of an accessible means of egress. Areas of refuge are not required for stairways/elevators accessed from a refuge area in conjunction with a horizontal exit clarifies that a redundant area of refuge is not needed immediately adjacent to the elevator where a refuge area and horizontal exit to the elevator are provided. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public.

Furthermore, the life safety concerns are already addressed by the increase fire protection features and constant supervision that is provided in group I-3 facilities. Per the 2012 edition of the IBC group I-3 occupancies are already exempted from area of refuge requirements per current exemption # 2 to 1007, which exempts buildings that are sprinkled per IBC section requires group I occupancies to be sprinkled per It is a valid argument that proposed exception #7 to 1007 is redundant therefore not needed; therefore our public comment proposes to delete exception #7 from the code change. The proposals text regarding horizontal exits and elevators is unaffected by this public comment. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as Areas of Study. The Area of Study for this code change and public comment is called IBC Coordination with the new ADAAG. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website Since its inception in April, 2005, the CTC has held twenty-four meetings all open to the public. In addition to holding face-to-face meetings, the CTC established Study Groups where any interested party can participate in conference calls on specific subjects such as this area of study without having to attend the face-to-face meetings.

88 E (IFC [B] ) Proposed Change as Submitted Proponent: Jerome Seville, Commonwealth of Pennsylvania representing self Revise as follows: (IFC [B] ) Platform lifts. Platform (wheelchair) lifts shall not serve as part of an accessible means of egress, except where allowed as part of a required accessible route in Section , Items 1 through 9. Platform lifts permitted to serve as part of an accessible route by Item 10 in Section shall not serve as part of an accessible means of egress for Group I-1 or I-2 facilities or where the exit will serve more than 200 occupants. Standby power shall be provided in accordance with Chapter 27 for platform lifts permitted to serve as part of a means of egress. Reason: There will be occupancies, even in new construction, where the only practical means of access into the structure will be by a wheelchair lift. With the entrance constituting one of the means of egress, it would be beneficial to allow the use of the lift to exit. Assisted living facilities, hospitals and nursing homes (Groups I-1 and I-2) have a higher excepted number of people that may have difficulty with stairways. The occupancy limit of 200 for other occupancies is being based upon IBC Section , where it is being assumed that there will be one wheelchair individual per 200 occupants; thus only one wheelchair in the area being evacuated by the lift. Cost Impact: None E-Seville.doc Public Hearing Results Committee Reason: This proposal does not seem to be consistent with the intent of accessibility and actually lessens access. If this allowing egress through this platform lift option is a concern, limiting to the option to just Group I-1 and I-2 does not seem sufficient. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Jerome Seville, Commonwealth of Pennsylvania representing self, requests Approval as Modified by this Public Comment. Replace the proposal as follows: (IFC [B] ) Platform lifts. Platform (wheelchair) lifts shall not serve as part of an accessible means of egress, except where allowed as part of a required accessible route in Section Items 1 through 9. In other than Group I-1 and I-2 occupancies, platform lifts allowed as part of a required accessible route in Section , Item 10 shall be permitted to serve as one of the accessible means of egress provided the occupant load of the area being served does not exceed 200. Standby power shall be provided in accordance with Chapter 27 for platform lifts permitted to serve as part of a means of egress. Commenter s Reason: Section , Item 10 allows for platform lifts to be used as part of an accessible route into a building where the existing site constraints make use of a ramp or elevator infeasible. There will be infills or complete changes of occupancies in urban areas, particularly in hilly jurisdictions, where the only practical means of access into the structure will be by a wheelchair lift. With the entrance constituting one of the means of egress, it would be beneficial to allow the use of the lift to exit for smaller buildings. Additionally, this text limits the use of the Item #10 allowance to only one of the accessible means of egress ICC FINAL ACTION AGENDA 1124

89 Because Section requires at least two accessible means of egress in most buildings. The second accessible means of egress would still be required to meet the provisions of Section The occupancy limit of 200 is consistent with IBC Section , which assumes only one person using a wheelchair in the area of the exit. ASME A18.1, to which standby power to a wheelchair lift must adhere to, mandates that if by battery the lift must be able to go five (5) complete cycles under full load. However, Group I-1 and I-2 occupancies should be excluded from this allowance since by their very nature; there could be a higher number of individuals in wheelchairs which may exceed the 5 cycle limit of the standby power source.

90 E (IFC [B] ) Proposed Change as Submitted Proponent: Steve Pfeiffer representing City of Seattle, Dept of Planning & Development Revise as follows: (IFC [B] ) Two-way communication. A two-way communication system complying with Sections and shall be provided at the landing serving each elevator landing or bank of elevators on each accessible floor that is one or more stories above or below the story of exit discharge. complying with Sections and Exceptions: 1. Two-way communication systems are not required at the landing serving each elevator landing or bank of elevators where the two-way communication system is provided within areas of refuge in accordance with Section Two-way communication systems are not required on floors provided with exit ramps conforming to the provisions of Section Reason: The purpose of this change is to clarify which elevator landings are required to have a two-way communication system where there are multiple elevators or banks of elevators on an accessible floor. The current language is clear where there is only one elevator, but if there are multiple elevators, it s unclear whether communication is required at one elevator, each elevator, or whether a communication device serving a bank of elevators would suffice. This change would require a single two-way communication at the landing for each single elevator or each bank of elevators on the floor. References to Sections and are also relocated as to more clearly apply to the communication system rather than the story of exit discharge. Cost Impact: The code change proposal will not increase the cost of construction E-Pfeiffer.doc Public Hearing Results Committee Action: Approved as Submitted Committee Reason: This revision will clarify that only a single two-way communication system is required at a group of elevators. However, there is a question if this language would now require two-way communication at the back-of-house service elevators, including freight elevators. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1126

91 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Gene Boecker, AIA, representing Code Consultants, Inc (CCI), and Rick Lupton, Dept. of Planning & Development representing City of Seattle, WA, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Two-way communication. A two-way communication system complying with Sections and shall be provided at the landing serving each elevator or bank of elevators on each accessible floor that is one or more stories above or below the story of exit discharge. Exceptions: 1. Two-way communication systems are not required at the landing serving each elevator landing or bank of elevators where the two-way communication system is provided within areas of refuge in accordance with Section Two-way communication systems are not required on floors provided with exit ramps conforming to the provisions of Section Two-way communications systems are not required at the landings serving only service elevators that are not designated as part of the accessible means of egress or serve as part of the required accessible route into a facility. 4. Two-way communications systems are not required at the landings serving only freight elevators. 5. Two-way communication systems are not required at the landing serving a private residence elevator. Commenter s Reason: The committee expressed concern that the language as written could be confusing relative to whether or not every elevator meant back-of-house elevators. The added two exceptions clarifies the original intent that service and fright elevators are not included. Exception #3 was worded in such a way that a service elevator would require the two-way communications system if it was the designated accessible means of egress off the floor or the required accessible route onto the floor. Freight elevators are not intended for passenger use and should not be required to have two-way communications system. Private residence elevators can only be used within individual dwelling units and the two-way communication system would not be practical.

92 E , , (IFC [B] , ) Proposed Change as Submitted Proponent: John Woestman, Kellen Company, representing Builders Hardware Manufacturers Association (BHMA) Add the definition as follows: SECTION 202 DEFINITIONS HORIZONTAL SLIDING ACCORDION FOLDING DOOR. An accordion-folding style multiple-section track-hung moveable door assembly. Revise as follows: (IFC [B] ) Door swing. Egress doors shall be of the pivoted or side-hinged swinging type. Exceptions: 1. Private garages, office areas, factory and storage areas with an occupant load of 10 or less. 2. Group I-3 occupancies used as a place of detention. 3. Critical or intensive care patient rooms within suites of health care facilities. 4. Doors within or serving a single dwelling unit in Groups R-2 and R In other than Group H occupancies, revolving doors complying with Section In other than Group H occupancies, horizontal sliding accordion folding doors complying with Section are permitted in a means of egress. 7. Power-operated doors in accordance with Section Doors serving a bathroom within an individual sleeping unit in Group R In other than Group H occupancies, manually operated horizontal sliding doors are permitted in a means of egress from spaces with an occupant load of 10 or less. Doors shall swing in the direction of egress travel where serving a room or area containing an occupant load of 50 or more persons or a Group H occupancy (IFC [B] ) Horizontal sliding accordion folding doors. In other than Group H occupancies, horizontal sliding accordion folding doors permitted to be a component of a means of egress in accordance with Exception 6 to Section shall comply with all of the following criteria: 1. The doors shall be power operated and shall be capable of being operated manually in the event of power failure. 2. The doors shall be openable by a simple method from both sides without special knowledge or effort. 3. The force required to operate the door shall not exceed 30 pounds (133 N) to set the door in motion and 15 pounds (67 N) to close the door or open it to the minimum required width. 4. The door shall be openable with a force not to exceed 15 pounds (67 N) when a force of 250 pounds (1100 N) is applied perpendicular to the door adjacent to the operating device. 5. The door assembly shall comply with the applicable fire protection rating and, where rated, shall be self-closing or automatic closing by smoke detection in accordance with Section , shall be installed in accordance with NFPA 80 and shall comply with Section The door assembly shall have an integrated standby power supply ICC FINAL ACTION AGENDA 1128

93 7. The door assembly power supply shall be electrically supervised. 8. The door shall open to the minimum required width within 10 seconds after activation of the operating device. Reason: This proposal is intended to clarify the IBC. Our BHMA members are seeing code officials, specifiers, and other stakeholders questioning or attempting to apply the requirements of to the doors included in Currently, both IBC Sections and could be (incorrectly) interpreted as applying to the same types of sliding doors (power-operated horizontal sliding doors). However, the intent of the code is that these sections apply to doors of significantly different configurations. The doors of are the more common power-operated doors such as the doors installed at the entrances to stores, businesses, hospitals, and the like. When a pedestrian is not present, these doors usually are in a closed position, and are powered open for passage, and then powered closed. The power operated doors included within the scope of the standards referenced in are rarely used where a fire-rated opening protective is required. The doors in are an accordion-style folding door assembly which slides horizontally. In the opening, these doors are usually kept in an open position like many other fire-rated doors or smoke-rated doors protecting elevator lobbies, or other gathering areas. The doors in may travel on a track in a straight line, but may also travel on a track that has a curve or curves. The proposed definition and text revisions are intended to not revise the technical requirements of the IBC. Cost Impact: None E-Woestman.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The proposal would eliminate design options for horizontal sliding doors. The definition could encompass room dividers. This proposal would only allow for one type of technology. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: John Woestman, Kellen Company, representing Builders Hardware Manufacturers Association (BHMA), requests Approval as Modified by this Public Comment. Modify the proposal as follows: SECTION 202 DEFINITIONS HORIZONTAL SLIDING ACCORDION FOLDING DOOR. An accordion-folding style multiple-section track-hung moveable door assembly (IFC [B] ) Door swing.

The door assembly power supply shall be electrically supervised. 8. The door shall open to the minimum required width within 10 seconds after activation of the operating device. Commenter s Reason: This proposal seeks to differentiate the means of egress requirements of the horizontal sliding doors addressed in Section of the IBC from other sections of the IBC addressing means of egress requirements of other horizontal sliding doors, and especially the power operated doors addressed by section No technical changes to the IBC are sought. This public comment attempts to address the committee s comments and stakeholder feedback regarding the proposal. Below are several examples of the horizontal sliding doors addressed by this section of the IBC (Section ). Door in normally-open position (left), and partially deployed (right). Source: Source: ICC FINAL ACTION AGENDA 1130

95 The doors addressed by Section are commonly in the normally-open position (hidden in their enclosure). In the event of fire or smoke, where these doors are installed in the means of egress, this section of the code requires the doors to be power operated but also openable manually to the required minimum egress width. Items 1 through 8 of Section when taken together, provide a unique set of requirements that apply only to doors of this type of configuration.

A revolving door used as other than a component of a means of egress shall comply with Section The collapsing breakout force of a revolving door not used as a component of a means of egress shall not be more than 180 pounds (801 N). Exception: A collapsing breakout force in excess of 180 pounds (801 N) is permitted if the collapsing force is reduced to not more than 130 pounds (578 N) when at least one of the following conditions is satisfied: 1. There is a power failure or power is removed to the device holding the door wings in position. 2. There is an actuation of the automatic sprinkler system where such system is provided. 3. There is an actuation of a smoke detection system which is installed in accordance with Section 907 to provide coverage in areas within the building which are within 75 feet ( mm) of the revolving doors. 4. There is an actuation of a manual control switch, in an approved location and clearly defined, which reduces the holding breakout force to below the not more than 130-pounds (578 N) force level. Add standard to Chapter 35 (IFC Chapter 80) as follows: BHMA A Power and Manual Operated Revolving Pedestrian Doors Reason: This proposal updates the requirements currently in the IBC for revolving doors and introduces the 2011 edition of BHMA A American National Standard for Power and Manual Operated Revolving Pedestrian Doors into the IBC. Revolving doors currently being installed in commercial buildings range from 6 feet to 24 feet in diameter and include manually operated revolving doors and numerous types and sizes of automatic revolving doors (i.e. power operated revolving doors). The latest edition of BHMA A includes in its scope a wide variety of manual and power operated revolving doors, many of which are not included within the scope of the current IBC requirements. The requirements in A include the maximum allowable door speed (RPM), based on type and size of revolving door, and ranges from maximum 12 RPM for the smallest manual revolving door to maximum 0.3 RPM for the largest power operated revolving door. BHMA A includes requirements for egress including minimum egress width and maximum breakout force, and also includes requirements for signage, glazing, sensors, an emergency stop switch, and other criteria. The existing Table is recommended to be deleted as there are five (5) expanded and updated tables in A addressing maximum allowable door speeds (RPM) for manually operated revolving doors and the various types and sizes of power operated revolving doors. Cost Impact: Proposal updates IBC to current industry standards and practices resulting in no cost impact. Analysis: A review of the standard proposed for inclusion in the code, BHMA A with regard to the ICC criteria for referenced standards (Section 3.6 of CP#28) will be posted on the ICC website on or before April 2, E-Woestman.doc 2012 ICC FINAL ACTION AGENDA 1133

98 Public Hearing Results Committee Action: Disapproved For staff analysis of the content of the BMHA A standard relative to CP#28, Section 3.6, please visit: : Committee Reason: The scope of the referenced standard, BMHA A , states that the standard is not for custom installation. There is some concern that this could be interpreted as not requiring compliance with the standard with any custom installation. The ICC Standards Review Committee felt that there were some non-mandatory language in the standard. The committee felt that Table in the code aided code official in determining compliance for revolving doors. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: John Woestman, Kellen Company, representing Builders Hardware Manufacturers Association (BHMA), requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Revolving doors. Revolving doors shall comply with the following: 1. Revolving doors shall comply with BHMA A and shall be installed in accordance with the manufacturer s installation instructions. 2. Each revolving door shall be capable of breakout in accordance with BHMA A and shall provide an aggregate width of not less than 36 inches (914 mm). 3. A revolving door shall not be located within 10 feet (3048 mm) of the foot of or top of stairs or escalators. A dispersal area shall be provided between the stairs or escalators and the revolving doors. 4. The revolutions per minute (rpm) for a revolving door shall not exceed the maximum rpm as specified in BHMA A Manual revolving doors shall comply with Table (1). Automatic or power operated revolving doors shall comply with Table (2). 5. An emergency stop switch shall be provided near each entry point of a automatic or power operated revolving doors within 48 inches (1220 mm) of the door and between 24 inches (610 mm) and 48 inches (1220 mm) above the floor. The activation area of the emergency stop switch button shall be not less than 1 inch (25 mm) in diameter and shall be red. 6. Each revolving door shall have a side-hinged swinging door which complies with Section in the same wall and within 10 feet (3048 mm) of the revolving door. 7. Revolving doors shall not be part of an accessible route required by Section 1007 and Chapter 11.

99 Table (2) (IFC [B] Table (2)) Maximum Door Speed Automatic or Power Operated Revolving Doors Revolving Door Maximum Nominal Diameter (ft-in) Maximum Allowable Revolving Door Speed (rpm) (Portion of proposal not shown remains unchanged.) Commenter s Reason: This proposal and public comment build on the existing requirements for revolving doors in the IBC, updates the IBC, and attempts to address the committee s comments. Revolving doors range from (smaller) manually operated revolving door systems to automatic (power operated) revolving doors of small to large diameter (8 to 24 diameter). Several types of revolving doors are illustrated below. Manual Revolving Doors (7 dia.) Automatic Revolving Door (8 dia.) Automatic Revolving Door (20 dia.) This proposal references BHMA A which includes the same egress-related requirements currently in the IBC (i.e. breakout function and maximum forces, etc.) and includes numerous additional safety-related requirements for revolving doors which are currently not required by the IBC. For example, BHMA A requires manually operated revolving doors to contain governors to limit the rotational speed of the door and requires automatic, or power operated, revolving doors to incorporate numerous sensors and switches, and complex motor controls to safely operate the door. Addressing the committee s reasons for disapproving this proposal: 1. Custom installations. Custom installation would likely be addressed in a manner similar to today. The mandatory requirements of this section of the IBC would apply (i.e. means of egress / breakout, emergency stop switches, maximum speed, etc.) as would the provisions of the proposed standard, BHMA A With approval of this proposal for the IBC, far fewer revolving door applications would not be addressed by IBC requirements. 2. Non-mandatory language in the proposed standard. ICC staff s analysis of the proposed standard states: No permissive or unenforceable language was noted. No proprietary references were noted. The standard indicates that it was developed through a consensus process. The consensus process is ANSI. However, the ICC Standard Review Committee found very occasional use of permissive language. Addressing the ICC SRC findings: in the proposed standard, the very occasional use of permissive language allows options for complying with mandatory requirements of the standard ICC FINAL ACTION AGENDA 1135

100 For example, sensors are required in specified locations on automatic revolving doors, and cushioning devices are also required in specified locations. The language in the standard allows these mandatory requirements to be met with the (required) sensor built into the (required) cushioning device, or the (required) sensor may be an item mounted separately from the (required) cushioning device. 3. Including Table in the code. Existing Table is replaced with two tables: one table for manual revolving doors, and a second table for automatic, or power operated, revolving doors. The table for automatic revolving doors is expanded to include revolving door diameters larger than currently included in Table , and the maximum allowable RPM is revised downward (slower) for safety reasons and to be consistent with the current industry standard, BHMA A BHMA A includes provisions for acceptable door speeds (max. RPM), egress / breakout requirements for the various types and configurations of revolving doors (consistent with current and proposed IBC requirements), glazing (consistent with Federal and IBC requirements for safety glazing), kinetic energy, and safety requirements such as emergency stop switches, sensors, and speed controls. These provisions enhance current IBC requirements. E56-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1136

103 Power-Operated Doors Three Examples Low Energy Power-Operated Doors To enhance accessibility in public buildings, side-hinged doors are commonly installed as low-energy power-operated doors. These doors operate at slower speeds and lower forces, compared to the faster moving power-operated door. Low energy poweroperated doors are commonly activated by pressing a push plate, and open fully once activated. In addition, these doors can be activated by pushing or pulling on the door itself, to cause the door to open fully. Notice the post mounted push plate, left image below, and the wall mounted push plate, right image below. Power-assisted doors Low Energy Power-Operated Doors Two Examples Power assisted doors reduce the force or effort it takes to open the door while it is being pushed or pulled. The user activates the door with a slight push or pull of the door handle. As soon as the push or pull force is removed, the door will start to close.

104 E (IFC [B] ) Proposed Change as Submitted Proponent: David R. Scott, AIA, representing Target Corporation Revise as follows: (IFC [B] ) Floor elevation. There shall be a floor or landing on each side of a door. Such floor or landing shall be at the same elevation on each side of the door. Landings shall be level except for exterior landings, which are permitted to have a slope not to exceed 0.25 unit vertical in 12 units horizontal (2-percent slope). Exceptions: 1. Doors serving individual dwelling units in Groups R-2 and R-3 where the following apply: 1.1 A door is permitted to open at the top step of an interior flight of stairs, provided the door does not swing over the top step. 1.2 Screen doors and storm doors are permitted to swing over stairs or landings. 2. Exterior doors as provided for in Section , Exception 1, and Section , which are not on an accessible route. 3. In Group R-3 occupancies not required to be Accessible units, Type A units or Type B units, the landing at an exterior doorway shall not be more than 73/4 inches (197 mm) below the top of the threshold, provided the door, other than an exterior storm or screen door, does not swing over the landing. 4. Variations in elevation due to differences in finish materials, but not more than 1/2 inch (12.7mm). 5. Exterior decks, patios or balconies that are part of Type B dwelling units, have impervious surfaces and that are not more than 4 inches (102 mm) below the finished floor level of the adjacent interior space of the dwelling unit. 6. Doors serving equipment spaces not required to be accessible in accordance with Section and serving an occupant load of 5 or less shall be permitted to have the landings on both sides to be at different levels provided the elevation difference is not more than 7 inches (178 mm). Reason: Equipment spaces are utilized by personal familiar with the layout and function of such space. This would not constitute a hazard type situation stepping down from the equipment spaces. Cost Impact: The code change proposal will not increase the cost of construction E-OLIPHANT Public Hearing Results Committee Action: Approved as Submitted Committee Reason: This options if preferred over E58. This proposal addresses the issue of type of space and limits occupant load. The people using this area will be familiar with the space, so the concern for the step/threshold as a tripping hazard is limited. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1140

105 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Eirene Oliphant, MCP, BRR Architecture, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Floor elevation. There shall be a floor or landing on each side of a door. Such floor or landing shall be at the same elevation on each side of the door. Landings shall be level except for exterior landings, which are permitted to have a slope not to exceed 0.25 unit vertical in 12 units horizontal (2-percent slope). Exceptions: 1. Doors serving individual dwelling units in Groups R-2 and R-3 where the following apply: 1.1 A door is permitted to open at the top step of an interior flight of stairs, provided the door does not swing over the top step. 1.2 Screen doors and storm doors are permitted to swing over stairs or landings. 2. Exterior doors as provided for in Section , Exception 1, and Section , which are not on an accessible route. 3. In Group R-3 occupancies not required to be Accessible units, Type A units or Type B units, the landing at an exterior doorway shall not be more than 73/4 inches (197 mm) below the top of the threshold, provided the door, other than an exterior storm or screen door, does not swing over the landing. 4. Variations in elevation due to differences in finish materials, but not more than 1/2 inch (12.7mm). 5. Exterior decks, patios or balconies that are part of Type B dwelling units, have impervious surfaces and that are not more than 4 inches (102 mm) below the finished floor level of the adjacent interior space of the dwelling unit. 6. Doors serving equipment spaces not required to be accessible in accordance with Section and serving an occupant load of 5 or less shall be permitted to have the landings a landing on both sides one side to be at different levels provided the elevation difference is not more than 7 inches (178 mm) above or below the landing on the egress side of the door. Commenter s Reason: The committee disapproved the E58 proposal believing that the proposed language would allow for both sides of the floor to be 7 inches below the threshold which would result in a 7 inch high threshold, thus creating a tripping hazard. The committee also suggested that a limit on the occupant load be provided. The only difference between E58 and E59 was the occupant load, otherwise the proposed code language was identical. The committee approved E59 due to the limited occupant load of 5. However, the tripping hazard language remains. This public comment is being provided in an effort to make sure the intent of the language was clear, that the floor level cannot be below 7 inches on both sides of the door.

106 E (IFC [B] ) Proposed Change as Submitted Proponent: Jeff Sprout, AIA, Target, representing Target Corporation Revise as follows: (IFC [B] ) Locks and latches. Locks and latches shall be permitted to prevent operation of doors where any of the following exists: 1. Places of detention or restraint. 2. In buildings in occupancy Group A having an occupant load of 300 or less, Groups B, F, M and S, and in places of religious worship, the main exterior door or doors are permitted to be equipped with key-operated locking devices from the egress side provided: 2.1. The locking device is readily distinguishable as locked; 2.2 A readily visible durable sign is posted on the egress side on or adjacent to the door stating: THIS DOOR TO REMAIN UNLOCKED WHEN BUILDING IS OCCUPIED. The sign shall be in letters 1 inch (25 mm) high on a contrasting background; and Exception: Buildings shall not be considered occupied after business hours in multiple-exit buildings where employees, security and cleaning crews have access to other exits without requiring the use of a key or in small buildings with one exit The use of the key-operated locking device is revokable by the building official for due cause. 3. Where egress doors are used in pairs, approved automatic flush bolts shall be permitted to be used, provided that the door leaf having the automatic flush bolts has no doorknob or surfacemounted hardware. 4. Doors from individual dwelling or sleeping units of Group R occupancies having an occupant load of 10 or less are permitted to be equipped with a night latch, dead bolt or security chain, provided such devices are openable from the inside without the use of a key or tool. 5. Fire doors after the minimum elevated temperature has disabled the unlatching mechanism in accordance with listed fire door test procedures. Reason: Provide clarification to the intent of the required signage in that it does not pertain to after business hours when employees, security and cleaning crews have access to other exits without requiring the use of a key or to small building that require only one exit. The above statement is supported by the code commentary as provided for Exception 2. Cost Impact: The code change proposal will not increase the cost of construction E-SPROUT Public Hearing Results Committee Action: Disapproved Committee Reason: The proposed language has not limited the number of employees that could be in the building after business hours. There are no qualifications for travel distances or number of exist available to staff when the front doors are locked. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1142

107 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Jeff Sprout, AIA, representing Target Corporation, requests Approval as Modified by this Public Comment. Modify the proposal as follows: Locks and latches. Locks and latches shall be permitted to prevent operation of doors where any of the following exist: 1. Places of detention or restraint. 2. In building in occupancy Group A having a occupant load of 300 or less, Groups B, F, M and S, and in placed of religious worship, the main door or doors are permitted to be equipped with key-operated locking devices from the egress side provided: 2.1. The locking device is readily distinguishable as locked; 2.2 A readily visible durable sign is posted on the egress side on or adjacent to the door stating: THIS DOOR TO REMAIN UNLOCKED WHEN BUILDING IS OCCUPIED. The sign shall be in letters 1 inch (25 mm) high on a contrasting background. For the purpose of this provision, buildings shall not be considered to be occupied after business hours; and 2.3 The use of a key-operated locking device is revocable by the building official for due cause. Exception: Buildings shall not be considered occupied after business hours in multiple-exit buildings where employees, security and cleaning crews have access to other exits without requiring the use of a key or in small buildings with one exit. 3. Where egress doors are used in pairs, approved automatic flush bolts shall be permitted to be used, provided that the door leaf having the automatic flush bolts has no doorknob or surface-mounted hardware. 4. Doors from individual dwelling or sleeping units of Group R occupancies having an occupant load of 10 or less are permitted to be equipped with a night latch, dead bolt or security chain, provided such devices are openable from the inside without the use of a key or tool. 5. Fire doors after the minimum elevated temperature has disabled the unlatching mechanism in accordance with the listed fire door test procedures. Commenter s Reason: Committee comments included how to address the number of employees in the building after business hours, as well as addressing qualifications for travel distances or number of exits available to staff when the front doors are locked. The code commentary indicates that the locking arrangement is only permitted on the main exit and therefore, the employees, security and cleaning crews will have access to other exits without requiring the use of a key. This allowance is also available to small buildings with just one exit. Inherently, the number of employees after business hour will be limited to a small number and who will be familiar with the building surroundings and location of other exits in multiple exit buildings. The location or these other exits would need to follow travel distance requirements elsewhere in the code. E64-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1143

108 E (IFC [B] ) Proposed Change as Submitted Proponent: Lee J. Kranz, City of Bellevue, Washington, representing Washington Association of Building Officials Technical Code Development Committee Revise as follows: (IFC [B] ) Locks and latches. Locks and latches shall be permitted to prevent operation of doors where any of the following exists: 1. Places of detention or restraint. 2. In buildings in occupancy Group A having an occupant load of 300 or less, Groups B, F, M and S, and in places of religious worship, the main exterior door or doors are permitted to be equipped with key-operated locking devices from the egress side provided: 2.1. The locking device is readily distinguishable as locked; 2.2. A readily visible durable sign is posted on the egress side on or adjacent to the door stating: THIS DOOR TO REMAIN UNLOCKED WHEN BUILDING IS OCCUPIED. The sign shall be in letters 1 inch (25 mm) high on a contrasting background; and 2.3. The use of the key-operated locking device is revokable by the building official for due cause. 3. Where egress doors are used in pairs, approved automatic flush bolts shall be permitted to be used, provided that the door leaf having the automatic flush bolts has no doorknob or surfacemounted hardware. 4. Doors from individual dwelling or sleeping units of Group R occupancies having an occupant load of 10 or less are permitted to be equipped with a night latch, dead bolt or security chain, provided such devices are openable from the inside without the use of a key or tool. 5. Fire doors after the minimum elevated temperature has disabled the unlatching mechanism in accordance with listed fire door test procedures. 6. Where occupants must re-enter the building for egress purposes, doors serving outdoor areas of Group R-3 occupancies and individual sleeping units or dwelling units of Group R-2 occupancies with an occupant load of 10 or less are permitted to be equipped with locks or latches provided such devices are openable from the inside without the use of a key or special knowledge or effort. 7. Egress doors serving outdoor areas having an occupant load of 300 or less where single or multiple paths of egress travel from the outdoor area are required to pass through the building are permitted to be equipped with locks or latches provided 7.1 The locking device is readily distinguishable as locked on the interior side. 7.2 A readily visible durable sign is posted on the interior side on or adjacent to the door stating: THIS DOOR TO REMAIN UNLOCKED WHEN THE OUTDOOR AREA IS OCCUPIED. The sign shall be in letters 1 inch high on a contrasting background. 7.3 The use of the key-operated locking device is revocable by the building official for due cause. Reasoning: Item #6: Currently there are no provision in the code that allow locks or latches to be installed on doors serving outdoor areas of R-3 or R-2 sleeping units or dwelling units where the occupants must re-enter the building for egress purposes. Exception #2 of IBC Section is unclear in this regard. It is common practice to install locks or latches on exterior doors serving these outdoor areas to maintain security. Occupant loads exceeding 10 persons would not be allowed to use the provision, similar to item #4 of this section. Item #7: Currently egress doors serving outdoor areas, where single or multiple paths of egress travel are required to pass through the building, are not permitted to have locks or latches. For security purposes, building owners or tenants typically install locks on required egress doors from these areas. When occupants must re-enter the building, as is typical for elevated decks where an exterior stair from the deck is impractical, IBC Section requires an unobstructed path of egress from these outdoor areas, similar to any occupied room in the building ICC FINAL ACTION AGENDA 1144

109 The sketch below illustrates this situation. The deck shown is on the 4 th floor of the building. The installation of an exterior stairway is not practical. The owner wants to lock the doors for security purposes but this is a problem because, per IBC Section , occupants must be able to egress from the deck at any time. Cost Impact: The code change proposal will increase the cost of construction. This is due to the cost of installing a sign above the door and a locking device which is distinguishable as locked #2-E-KRANZ Public Hearing Results Committee Action: Disapproved Committee Reason: There are other alternatives available to allow for this real world condition of outdoor areas exiting through a building. For new item 6, what is the justification for not allowing key locks for private balconies? There was no justification for the 300 occupant load limit in new Item 7. Since these are such different issues, they should be submitted as separate code changes. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1145

110 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Lee J Kranz, City of Bellevue Washington, representing WABO TCD, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Locks and latches. Locks and latches shall be permitted to prevent operation of doors where any of the following exists: 1. Places of detention or restraint. 2. In buildings in occupancy Group A having an occupant load of 300 or less, Groups B, F, M and S, and in places of religious worship, the main exterior door or doors are permitted to be equipped with key-operated locking devices from the egress side provided: 2.1. The locking device is readily distinguishable as locked; 2.2. A readily visible durable sign is posted on the egress side on or adjacent to the door stating: THIS DOOR TO REMAIN UNLOCKED WHEN BUILDING IS OCCUPIED. The sign shall be in letters 1 inch (25 mm) high on a contrasting background; and 2.3. The use of the key-operated locking device is revokable by the building official for due cause. 3. Where egress doors are used in pairs, approved automatic flush bolts shall be permitted to be used, provided that the door leaf having the automatic flush bolts has no doorknob or surface-mounted hardware. 4. Doors from individual dwelling or sleeping units of Group R occupancies having an occupant load of 10 or less are permitted to be equipped with a night latch, dead bolt or security chain, provided such devices are openable from the inside without the use of a key or tool. 5. Fire doors after the minimum elevated temperature has disabled the unlatching mechanism in accordance with listed fire door test procedures. 6. Where occupants must re-enter the building for egress purposes, doors serving outdoor areas of Group R-3 occupancies and individual sleeping units or dwelling units of Group R-2 occupancies with an occupant load of 10 or less are permitted to be equipped with locks or latches provided such devices are openable from the inside without the use of a key or special knowledge or effort Egress doors serving outdoor areas having an occupant load of or less where single or multiple paths of egress travel from the outdoor area are required to pass through the building are permitted to be equipped with locks or latches provided: The locking device is readily distinguishable as locked on the interior side; A readily visible durable sign is posted on the interior side on or adjacent to the door stating: THIS DOOR TO REMAIN UNLOCKED WHEN THE OUTDOOR AREA IS OCCUPIED. The sign shall be in letters 1 inch high on a contrasting background; 6.3 A two-way communication system complying with Sections and shall be provided on the egress side The use of the key-operated locking device is revocable by the building official for due cause. Commenter s Reason: IBC Section requires an unobstructed path of egress from outdoor areas where single or multiple paths of egress travel are required to pass through the building. This is typical of any occupied room in the building when the path of egress travel must be through the building. Currently egress doors serving outdoor areas are not permitted to have locks or latches. For security purposes, building owners or tenants typically install locks on required egress doors from these areas in violation of the code. Many building officials allow the locks and latches on doors serving the outdoor areas using the modification provisions of Sections & Since this situation occurs on a regular basis it makes sense to provide a reasonable standard for safety of the occupants. The MOE Committee in Dallas made 3 suggestions to modify this proposal. They include: 1) elimination of item #6 permitting locks and latches on R-2 and R-3 outdoor areas, 2) reduce the maximum occupant load of the outdoor area in item #7, and 3) include provision for a two-way communication device accessible from the outdoor area. All 3 of these suggestions have been made to the attached public comment. The two-way communication system requirements are currently included in IBC Section & Section specifies connection to a fire command center or central control point approved by the fire department. If the central control point is not constantly attended then connections to a monitoring location or 911 dispatch is permitted. Approval of the revised proposal is recommended.

111 E (IFC [B] ) Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: (IFC [B] ) Special locking arrangements in doors in Group Groups I-1 assisted living facilities and I-2. Approved, special egress locks shall be permitted in a Group I-1 assisted living facilities or I-2 occupancy occupancies where the clinical needs of persons receiving care require such locking. Special egress locks shall be permitted in such occupancies where the building is equipped throughout with an automatic sprinkler system in accordance with Section or an approved automatic smoke or heat detection system installed in accordance with Section 907, provided that the doors are installed and operate in accordance with Items 1 through 7 below. 1. The doors unlock upon actuation of the automatic sprinkler system or automatic fire detection system. 2. The doors unlock upon loss of power controlling the lock or lock mechanism. 3. The door locks shall have the capability of being unlocked by a signal from the fire command center, a nursing station or other approved location. 4. A building occupant shall not be required to pass through more than one door equipped with a special egress lock before entering an exit. 5. The procedures for the operation(s) of the unlocking system shall be described and approved as part of the emergency planning and preparedness required by Chapter 4 of the International Fire Code. 6. All clinical staff shall have the keys, codes or other means necessary to operate the locking devices. 7. Emergency lighting shall be provided at the door. Exception: Items 1 through 4 shall not apply to doors to areas where persons which because of clinical needs require restraint or containment as part of the function of a psychiatric treatment area. Reason: The current text allows special provisions in the path of egress for Group I-2 when patient care, most often due to issues of elopement, allows for staff to control access to the exits. This allowance should be permitted in assisted living facilities in order to allow proper care for residents in the initial stages of Alzheimer s, therefore, this allowance needs to be extended to Group I-1 assisted living facilities. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party.

Modify the proposal as follows: (IFC [B] ) Special locking arrangements in doors in Groups I-1 assisted living facilities and I-2. Approved, special egress locks shall be permitted in a Group I-1 assisted living facilities or I-2 occupancies where the clinical needs of persons receiving care require such locking. Special egress locks shall be permitted in such occupancies where the building is equipped throughout with an automatic sprinkler system in accordance with Section or an approved automatic smoke or heat detection system installed in accordance with Section 907, provided that the doors are installed and operate in accordance with Items 1 through 7 below. 1. The doors unlock upon actuation of the automatic sprinkler system or automatic fire detection system. 2. The doors unlock upon loss of power controlling the lock or lock mechanism. 3. The door locks shall have the capability of being unlocked by a signal from the fire command center, a nursing station or other approved location. 4. A building occupant shall not be required to pass through more than one door equipped with a special egress lock before entering an exit. 5. The procedures for the operation(s) of the unlocking system shall be described and approved as part of the emergency planning and preparedness required by Chapter 4 of the International Fire Code. 6.

Exception: Items 1 through 4 shall not apply to doors to areas where persons which because of clinical needs require restraint or containment as part of the function of a psychiatric treatment area. Commenter s Reason: Elopement potential exists in all Group I-1, therefore this option should not be limited to just assisted living. This would not affect revisions made to this section in E67, which clarified the requirements for this type of lock.

113 E (IFC [B] ) Proposed Change as Submitted Proponent: John Williams, CBO, Chair, ICC Ad Hoc Committee on Health Care and Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: (IFC [B] ) Special locking arrangements in Group I-2. Approved, special egress locks shall be permitted in a Group I-2 occupancy where the clinical needs of persons receiving care require such locking. Special egress locks shall be permitted in such occupancies where the building is equipped throughout with an automatic sprinkler system in accordance with Section or an approved automatic smoke or heat detection system installed in accordance with Section 907, provided that the doors are installed and operate in accordance with Items 1 through 7 below. 1. The doors unlock upon actuation of the automatic sprinkler system or automatic fire detection system. 2. The doors unlock upon loss of power controlling the lock or lock mechanism. 3. The door locks shall have the capability of being unlocked by a signal from the fire command center, a nursing station or other approved location. 4.

The procedures for the operation(s) of the unlocking system shall be described and approved as part of the emergency planning and preparedness required by Chapter 4 of the International Fire Code. 6. All clinical staff shall have the keys, codes or other means necessary to operate the locking devices. 7. Emergency lighting shall be provided at the door. Exception Exceptions: 1. Items 1 through 4 shall not apply to doors to areas where persons which because of clinical needs require restraint or containment as part of the function of a psychiatric treatment area. 2. Items 1 through 4 shall not apply to doors to areas where a listed egress control system is utilized to reduce the risk of child abduction. Reason: This section deals with the use of electric locks to enhance the capabilities of egress control. Egress control serves three primary purposes. These are to control the elopement of ambulatory patients not capable of self preservation; the containment of patients that, due to their mental condition, could do harm to others; the prevention of the abduction of babies and children. Exceptions allow for the use of listed child abduction security systems and even mechanical locks (non-electric.) This proposal is submitted by the ICC Ad Hoc Committee for Healthcare (AHC). The AHC was established by the ICC Board of Directors to evaluate and assess contemporary code issues relating to hospitals and ambulatory healthcare facilities. The AHC is composed of building code officials, fire code officials, hospital facility engineers, and state healthcare enforcement representatives.

Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment 1: John Williams, Adhoc Health Care MOE study group, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Special locking arrangements in Group I-2. Approved, special egress locks shall be permitted in a Group I-2 occupancy where the clinical needs of persons receiving care require such locking. Special egress locks shall be permitted in such occupancies where the building is equipped throughout with an automatic sprinkler system in accordance with Section or an approved automatic smoke or heat detection system installed in accordance with Section 907, provided that the doors are installed and operate in accordance with Items 1 through 7 below. 1. The doors unlock upon actuation of the automatic sprinkler system or automatic fire detection system. 2. The doors unlock upon loss of power controlling the lock or lock mechanism. 3. The door locks shall have the capability of being unlocked by a signal from the fire command center, a nursing station or other approved location. 4. A building occupant shall not be required to pass through more than one door equipped with a special egress lock before entering an exit. 5. The procedures for the operation(s) of the unlocking system shall be described and approved as part of the emergency planning and preparedness required by Chapter 4 of the International Fire Code. 6. All clinical staff shall have the keys, codes or other means necessary to operate the locking devices. 7. Emergency lighting shall be provided at the door. Exceptions: 1. Items 1 through 4 shall not apply to doors to areas where persons which because of clinical needs require restraint or containment as part of the function of a treatment area. 2. Items 1 through 4 shall not apply to doors to areas where a listed egress control system is utilized to reduce the risk of child abduction from nursery and obstetric areas of a Group I-2 hospital. Commenter s Reason: This issue of protection against child abduction is an important one for hospitals. However, we also understand the code development committee s concern that the proposed exception could be read to allow for an entire hospital to be locked down. The modification will limit these systems to the high risk areas of the nursery and obstetric areas only.

The procedures for the operation(s) of the unlocking system shall be described and approved as part of the emergency planning and preparedness required by Chapter 4 of the International Fire Code. 6. All clinical staff shall have the keys, codes or other means necessary to operate the locking devices. 7. Emergency lighting shall be provided at the door. Exceptions: 1. Items 1 through 4 shall not apply to doors to areas where persons which because of clinical needs require restraint or containment as part of the function of a treatment area. 2. Items 1 through 4 shall not apply to doors to areas where a listed egress control system is utilized to reduce the risk of child abduction from maternity, pediatric, or adolescent units in a Group I-2 hospital. Commenter s Reason: The proposal as submitted by John Williams, CBO, Chair, ICC Ad Hoc Committee on Healthcare should be accepted as modified. The committee made a reasonable recommendation to limit the areas in healthcare where there types of systems should be allowed. The modified language is provided to meet the request of the committee in order to gain adoption. I am submitting this request on behalf of the Wisconsin Healthcare Engineers Association Codes & Standards committee representing over 700 members in the State of Wisconsin.

116 E (IFC [B] ) Proposed Change as Submitted Proponent: John Williams, CBO, Chair, ICC Ad Hoc Committee on Health Care and Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: (IFC [B] ) Delayed egress locks. Approved, listed, delayed egress locks locking systems, shall be permitted to be installed on doors serving any occupancy except Group A, E, and H occupancies in buildings that are equipped throughout with an automatic sprinkler system in accordance with Section or an approved automatic smoke or heat detection system installed in accordance with Section 907, provided that the doors unlock in accordance with Items 1 through 6 below. A building occupant shall not be required to pass through more than one door equipped with a delayed egress lock before entering an exit. 1. The doors unlock upon actuation of the automatic sprinkler system or automatic fire detection system. 2. The doors unlock upon loss of power controlling the lock or lock mechanism. 3. The door locks shall have the capability of being unlocked by a signal from the fire command center. 4. The initiation of an irreversible process which will release the latch in not more than 15 seconds when a force of not more than 15 pounds (67 N) is applied for 1 second to the release device. Initiation of the irreversible process shall activate an audible signal in the vicinity of the door. Once the door lock has been released, by the application of force to the releasing device, relocking rearming shall be by manual means only. Exception: Where approved, a delay of not more than 30 seconds is permitted on a delayed egress door. 5. A sign shall be provided on the door located above and within 12 inches (305mm) of the release device reading: PUSH UNTIL ALARM SOUNDS. DOOR CAN BE OPENED IN 15 (30) SECONDS. Exception: Where approved, the installation of a sign is not required when it interferes with the safety of the residents in Group I occupancies. 6. Emergency lighting shall be provided at the door. Reason: The intent is for all proposals for Section to work together. Three changes are submitted in order to keep the discussions separate. The new exception to Item 5 - Providing escape instructions to first stage Alzheimer s disease patients who often still can read is unwise. Staff is there to assist in a fire. This proposal is submitted by the ICC Ad Hoc Committee for Healthcare (AHC). The AHC was established by the ICC Board of Directors to evaluate and assess contemporary code issues relating to hospitals and ambulatory healthcare facilities. The AHC is composed of building code officials, fire code officials, hospital facility engineers, and state healthcare enforcement representatives. The goals of the committee are to ensure that the ICC family of codes appropriately addresses the fire and life safety concerns of a highly specialized and rapidly evolving healthcare delivery system. This process is part of a joint effort between ICC and the American Society for Healthcare Engineering (ASHE), a subsidiary of the American Hospital Association, to eliminate duplication and conflicts in healthcare regulation. Since its inception in April, 2011, the AHC has held 5 open meetings and over 80 workgroup calls which included members of the AHC as well as any interested party to discuss and debate the proposed changes. All meeting materials and reports are posted on the AHC website at: This proposal is being co-sponsored by the ICC Code Technology Committee.

Cost Impact: None #1-E-WILLIAMS-ADHOC.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The signage is necessary at doors with delayed egress locking systems for visitors within the Group I-1 facilities. Disapproval is consistent with committee action on E Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: John Williams, Adhoc Health Care MOE study group, requests Approval as Modified by this Public Comment. Modify the proposal as follows: IBC (IFC [B] ) Delayed egress locks. Approved, listed, delayed egress locking systems, shall be permitted to be installed on doors serving any occupancy except Group A, E, and H occupancies in buildings that are equipped throughout with an automatic sprinkler system in accordance with Section or an approved automatic smoke or heat detection system installed in accordance with Section 907, provided that the doors unlock in accordance with Items 1 through 6 below. A building occupant shall not be required to pass through more than one door equipped with a delayed egress lock before entering an exit. 1.

A sign shall be provided on the door located above and within 12 inches (305mm) of the release device reading: PUSH UNTIL ALARM SOUNDS. DOOR CAN BE OPENED IN 15 (30) SECONDS. Exception: Where approved, in Group I occupancies, the installation of a sign is not required when the instructions compromise the safety of the residents in Group I occupancies where persons who because of clinical needs require restraint or containment as part of the function of the treatment area. 6. Emergency lighting shall be provided at the door. Commenter s Reason: When housing dementia patient, especially first stage Alzheimer patients, reading is often still in their capabilities. They are ambulatory, often in good physical condition, but not capable of self preservation. Their greatest dangers are elopement into traffic, ice and snow, darkness and wildlife. The intent of the proposed exception is to address this important safety issue. Families are relying on these facilities to keep their loved ones safe. Allowance for this exception is where approved by the code official. The MOE committee had a concern that the instruction signage at delayed egress locks was needed for visitors. In all Group I facilities, staff is trained to assist in evacuation of all occupants, including residents and visitors. In addition, delayed egress systems already include connection to both the sprinkler system and the fire detection system, both required under this section. In the event of a activation of the fire alarm or sprinkler system or power failure, all delayed egress doors unlock from the inside and allow unobstructed egress. Dementia units are staffed to assist residents and visitors in fire and weather emergencies with practiced emergency plans. Having a direct signage at the door adds to the likelihood that there will be elopements. All doors with delayed egress systems will still be required to have exit signs ICC FINAL ACTION AGENDA 1153

118 Where facilities that are faced with a choice between delayed egress with escape instructions at each door, or going to a full lockdown such as controlled egress, the facility will always pick pursuit of the latter due to concerns for patient safety. Several of the locking options do allow locking occupants in where there are staff releases the locks. This option would allow a facility to address patient safety without totally relying on staff to open exit doors in a fire event.

119 E (New) [IFC [B] (New)] Proposed Change as Submitted Proponent: Bryan M Romney, Building Official, University of Utah, Salt Lake City, Utah, representing self Add new text as follows: (IFC [B] ) Security locking arrangements. Approved special security egress locking systems shall be permitted on Group A occupancies including, but not limited to, museums, art galleries, special collections libraries and courtrooms; and Group B or M occupancies; for doors in the means of egress serving rooms or spaces where security needs of persons or building contents required such locking. Special egress locks shall be permitted in these occupancies where the building is equipped throughout with an automatic sprinkler system in accordance with Section or an approved automatic smoke or heat detection system installed in accordance with Section 907, provided that the doors are installed and operate in accordance with all of the following: 1. The doors unlock upon actuation of the automatic sprinkler system or automatic fire detection system. 2. The doors unlock upon loss of power controlling the lock or lock mechanism. 3. The door locks shall have the capability of being unlocked by a signal from an approved location that is constantly attended when the building is occupied. 4. Doors equipped with a security locking arrangement are monitored by either direct line of sight or remote monitoring from the constantly attended station. 5. A building occupant shall not be required to pass through more than one door equipped with a special security egress locking system before entering an exit. 6. The procedures for the operation of the special security egress locking system shall be described and approved as part of the emergency planning and preparedness required by Chapter 4 of the International Fire Code. 7. All security staff or persons identified in the procedures for Item 6 shall have the keys, codes, or other means necessary to operate the locking devices. 8. Emergency lighting shall be provided at the door. (Renumber subsequent sections) Reason: Chapter 10 does not provide a method for special locking or controlled egress except for Group I-1 and I-3 Occupancies. Other occupancy groups have needs for special locking arrangements either for securing persons or building contents. Examples include courtrooms where people poising a flight risk need special secure egress considerations. Research labs and animal housing facilities frequently require controlled egress systems such as card of biometric ingress and egress control systems. Libraries with rare book collections, art galleries, museums or mercantile occupancies where building contents area at risk of being stolen have needs for special security egress locking systems. This code addition would permit the code official to approve special locking arrangements in other occupancy groups where a demonstrated need exists. The procedure by which the special locking arrangement functions is to be reviewed and approved by the code official as outlined in Item 6. This item would allow the code official to approve special security egress locking systems under prescriptive requirement of Chapter 10 without having to approve an alternate design or method outlined in Section This code addition represents a significantly more defensible code provisions than the more interpretive alternative design route. This code addition allows an already existing code provisions for controlled egress doors in Group I-2 occupancies to be allowed for other occupancy groups where a demonstrated need exists. No new or unproven code protocol is created in this code addition, only an existing, proven, and verified provision is being extended to other occupancy groups which for years have had critically security needs not allowed by the code. Cost Impact: No initial construction cost impact. The IFC may require ongoing inspections of the Chapter 4 emergency planning and preparedness protocol compliance E-ROMNEY.doc 2012 ICC FINAL ACTION AGENDA 1155

120 Public Hearing Results Committee Action: Disapproved Committee Reason: The allowance for this type of locking arrangement for all Group B and M is too broad. In areas where high security is needed, allowances for this suggested type of locking arrangement could be addressed through alternative means. Stronger approval language is needed. A reference to UL294 would be consistent with other committee actions to the locking options. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Bryan M. Romney, University of Utah representing self, requests Approval as Modified by this Public comment. Modify the proposal as follows: (IFC [B] ) Security locking arrangements. Approved Special security egress locking systems shall be permitted when approved by building official in Group A-3, B, and M Occupancies on Group A including, but not limited to museums, art galleries, special collections libraries and courtrooms; and Group B, or M occupancies; for doors in the means of egress serving rooms or spaces where security needs of persons or building contents required require such locking. Special egress locks shall be permitted in such occupancies where the building is equipped throughout with an automatic sprinkler system in accordance with Section or an approved automatic smoke or heat detection system installed in accordance with Section 907, provided that the doors are installed and operate in accordance with all of the following: Items 1 through The doors unlock upon actuation of the automatic sprinkler system or automatic fire detection system. 2. The doors unlock upon loss of power controlling the lock or lock mechanism. 3. The door locks shall have the capability of being unlocked by a signal from an approved location that is constantly attended when the building is occupied. 4. Doors equipped with a security locking arrangement are monitored by either direct line of sight or remote monitoring from the constantly attended station. 5. A building occupant shall not be required to pass through more than one door equipped with a special security egress locking system before entering an exit. 6. The procedures for the operation of the special security egress locking system shall be described and approved as part of the emergency planning and preparedness required by Chapter 4 of the International Fire Code. 7. All security staff or persons identified in the procedures for Item 6 shall have the keys, codes, or other means necessary to operate the locking devices. 8. Emergency lighting shall be provided at the door. 9. All components of door locking system shall be listed in accordance with UL 294. (Renumber subsequent sections) Commenter s Reason: Chapter 10 does not provide a method for special locking or controlled egress except for Group I-2 (Section ) and Correctional Facility (Section ) Occupancies. Other occupancy groups have needs for special locking arrangements either for securing persons or building contents. Examples include courtrooms where people posing a flight risk need special secure egress considerations. Research labs and animal housing facilities frequently require controlled egress systems such as card or biometric ingress and egress control systems. Libraries with rare book collections, art galleries, museums or mercantile occupancies where building contents are at risk of being stolen have needs for special security egress locking systems. Airports frequently control egress from terminal and concourse areas to prevent unauthorized access to exterior flight deck or tarmac areas. This code addition would allow the code official to approve special locking arrangements in Occupancy Groups A-3, B, and M where a demonstrated need exists. The intent of this special security egress locking system is to control egress under normal building conditions and not restrict egress under emergency situations. Item 6 requires the protocol for operation of this system to be reviewed and approved by the code official. This code change would allow the code official to approve special security egress locking systems under the prescriptive requirements of Chapter 10 without having to deal with the risks of an alternate design or method outlined in Section This code addition represents a significantly more defensible code provision than the more interpretive alternative design method. This code addition allows an already existing code provision for controlled egress doors in Group I-2 occupancies (Section ) to be extended to other occupancy groups where a demonstrated need exists. No new or unproven code protocol is created in this code change; only an existing, proven, and verified protocol is being extended to other occupancy groups which have 2012 ICC FINAL ACTION AGENDA 1156

121 equally critical security needs not permitted by the code. This code addition will provide a means for the code official to approve a special locking system at the design stage rather than discovering a noncompliant locking system during final inspection or after the Certificate of Occupancy is issued. The Means of Egress Committee rejected the original proposed code change in Dallas because it was felt that the proposed code section was too broad and open-ended. This public comment by the proponent is to address both of the Committee s concerns and limit the usage of controlled egress systems to specific occupant groups with low to medium fire hazard ratings. The proponent also added to the original proposal that the building official is to approve all applications of the controlled egress system, thus eliminating an expectation of entitlement. The proponent added the requirement that the door locking system is to comply with UL 294. This standard is included so as to be consistent with other locking systems found in Chapter 10. The proponent has the endorsement of Bonneville and Utah Chapters of ICC. E76-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1157

122 E (New), (New), (New) [IFC (New), (New), (New)] Proposed Change as Submitted Proponent: Lee J. Kranz, City of Bellevue, Washington, representing Washington Association of Building Officials Technical Code Development Committee Add new text as follows: (IFC [B] ) Standpipes. Class 1 standpipe hose connections shall be provided in accordance with Item 1 or 5 of Section and NFPA 14. (Renumber subsequent sections) (IFC [B] ) Standpipes. Class 1 standpipe hose connections shall be provided in accordance with Item 3 of Section and NFPA (IFC [B] ) Standpipes. Class 1 standpipe hose connections shall be provided in accordance with Item 2 of Section and NFPA 14. (Renumber subsequent sections) Reason: Placing references to Section and NFPA 14 standpipe requirements in exit stairways, horizontal exits and exit passageways will help designers and reviewers to include this requirement early in the design process. During the means of egress design process, the requirement for standpipes for horizontal exits and exit passageways are frequently overlooked and may have significant cost impacts to correct. Including the standpipe references in Sections 1023 and 1025 will make the design team aware of the requirement early in the design process and help insure cost impacts are considered at the appropriate time. Adding the requirement in Section 1022 is for consistency. The intent is to have an IFC change to clarify that standpipes should be located within the enclosure for interior exit stairways. Literally the current text, by saying all required stairways, would require standpipes on exit access stairways and exterior exit stairway. If it is felt that standpipes should be provided in these locations, a modification would be to add this same language in a new Section for exit access stairways and for exterior exit stairways. Cost Impact: None E-Kranz.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The committee agreed that placement of stand pipes in a building is an important element that sometimes can be missed during the planning stage/building review. However, the proposed text could be interpreted to require stand pipes for all buildings, not just where required. It was suggested that a more appropriate reference would be Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1158

123 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Lee J. Kranz, City of Bellevue Washington representing Washington Association of Building Officials Technical Code Development Committee, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Standpipes. Where required by IBC Section 905.4, item 1 or 5, Class 1 standpipe hose connections shall be installed provided in accordance with Item 1 or 5 of Section and NFPA 14. (Renumber subsequent sections) Standpipes. Where required by IBC Section 905.4, item 3, Class 1 standpipe hose connections shall be installed provided in accordance with IBC Section 905.4, item 3 and NFPA Standpipes. Where required by IBC Section 905.4, item 2, Class 1 standpipe hose connections shall be installed provided in accordance with IBC Section 905.4, item 2 and NFPA 14. (Renumber subsequent sections) Commenter s Reason: The MOE Committee in Dallas agreed that placing references to the standpipe provisions in Sections 1022, 1023 and 1025 was important but indicated that the text, as submitted, could be interpreted to require standpipes in all situations where interior exit stairways, exit passageways or horizontal exits were provided, regardless of the exceptions contained in Section The provisions have been re-worded to clarify the intent. Placing references to Section standpipe requirements in sections 1022, 1023 and 1025 will help designers and reviewers to be aware of this important requirement and will insure that the standpipes, if required, are considered early in the design process to reduce costs during construction.

124 E (IFC [B] ) Proposed Change as Submitted Proponent: Robert J Davidson, Davidson Code Concepts LLC, representing self (rjd@davidsoncodeconcepts.com) Revise as follows: (IFC [B] ) Exit access stairways. Floor openings between stories created by exit access stairways shall be enclosed. Exceptions: 1. In other than Group I-2 and I-3 occupancies, exit access stairways that serve, or atmospherically communicate between, only two stories, are not required to be enclosed. 2. Exit access stairways serving and contained within a single residential dwelling unit or sleeping unit in Group R-1, R-2 or R-3 occupancies are not required to be enclosed. 3. In buildings with only Group B or M occupancies, exit access stairway openings are not required to be enclosed provided that the building is equipped throughout with an automatic sprinkler system in accordance with Section , the area of the floor opening between stories does not exceed twice the horizontal projected area of the exit access stairway, and the opening is protected by a draft curtain and closely spaced sprinklers in accordance with NFPA In other than Groups B and M occupancies, exit access stairway openings are not required to be enclosed provided that the building is equipped throughout with an automatic sprinkler system in accordance with Section , the floor opening does not connect more than four stories, the area of the floor opening between stories does not exceed twice the horizontal projected area of the exit access stairway, and the opening is protected by a draft curtain and closely spaced sprinklers in accordance with NFPA Exit access stairways within an atrium complying with the provisions of Section 404 are not required to be enclosed. 56. Exit access stairways and ramps in open parking garages that serve only the parking garage are not required to be enclosed. 67. Stairways serving outdoor facilities where all portions of the means of egress are essentially open to the outside are not required to be enclosed. 78. Exit access stairways serving stages, platforms and technical production areas in accordance with Sections and are not required to be enclosed. 89. Stairways are permitted to be open between the balcony, gallery or press box and the main assembly floor in occupancies such as theaters, places of religious worship, auditoriums and sports facilities. 910.In Group I-3 occupancies, exit access stairways constructed in accordance with Section are not required to be enclosed. Reason: The purpose of this code change is to delete the allowance for connecting up to four stories with an unenclosed exit access stairway. This language is the result of a re-write of code language last cycle that was purported to be editorial in nature. When I attempted to point out this change was expanding allowance of the connection of four stories in testimony at the final action hearings I was repeatedly interrupted by the supporters of the proposal and in their testimony they denied there was a change or increase in the allowance for interconnecting floor levels. If you review the previous language found in the 2009 IBC at Section 708.2, Exception 2 you will find that this allowance did not permit a stairway that was a portion of the means of egress to be unenclosed under this concept. Since an extra stairway not need for, nor allowed to be considered a portion of the means of egress, would be an added cost that used up valuable square footage, this application of the code was rare. (That is if in fact it was done as provided for by the code and no credit for egress including travel distance was taken) 2012 ICC FINAL ACTION AGENDA 1160

125 2009 International Building Code Shaft enclosure required. Openings through a floor/ceiling assembly shall be protected by a shaft enclosure complying with this section. Exceptions: 2. A shaft enclosure is not required in a building equipped throughout with an automatic sprinkler system in accordance with Section for an escalator opening or stairway that is not a portion of the means of egress protected according to Item 2.1 or Where the area of the floor opening between stories does not exceed twice the horizontal projected area of the escalator or stairway and the opening is protected by a draft curtain and closely spaced sprinklers in accordance with NFPA 13. In other than Groups B and M, this application is limited to openings that do not connect more than four stories. With the revised language the code now allows unenclosed exit access stairways to connect up to four stories of a building. This is a major technical change; it allows the use of unenclosed stairways that ARE part of the means of egress. The purpose of adding the term exit access stairway to the code was to provide for recognition of the stairs for use in exit access provided the travel distance was measured. See 2012 IBC, Section below. So we find that the change was not just editorial, it was a significant reduction in safety provided from the spread of smoke or heat International Building Code Exit access stairways and ramps. Travel distance on exit access stairways or ramps shall be included in the exit access travel distance measurement. The measurement along stairways shall be made on a plane parallel and tangent to the stair tread nosings in the center of the stair and landings. The measurement along ramps shall be made on the walking surface in the center of the ramp and landings. The problem with this section is not just a matter of increased allowances from one edition to another contrary to presentation. The section in question, 2012 IBC, Section Exception 4, is in direct conflict with the atrium provisions of Section wherein additional fire protection features are required when we have an atrium, which is defined as an opening connecting two or more stories other than enclosed stairways etc. Actually, if you apply the allowance for connecting floor levels with unenclosed stairs, you currently have an atrium by definition and design both in the older edition of the code and the present edition. Also note that there is no qualifier as to the size of an opening when dealing with atriums. It is just recognition that we have an opening that can allow the upward travel of smoke and heat due to the lack of an enclosing shaft. SECTION 404 ATRIUMS General. In other than Group H occupancies, and where permitted by Section , the provisions of Sections through shall apply to buildings or structures containing vertical openings defined as Atriums. ATRIUM. An opening connecting two or more stories other than enclosed stairways, elevators, hoistways, escalators, plumbing, electrical, air-conditioning or other equipment, which is closed at the top and not defined as a mall. Stories, as used in this definition, do not include balconies within assembly groups or mezzanines that comply with Section 505. Now objectors may argue that this is a matter of two different features, but a plain reading of the definition of an atrium and recognition of why we add fire protection features regardless of the size of the atrium clearly identifies that there is no difference. Whether I have a large atria with an open stairway in the middle, or a small atria with a stairway up through it does not change the fact that it is a path upward for smoke and heat. Since the atrium and the unenclosed exit access stairs present the same hazard, upward travel of smoke and heat, why such a major difference in the required fire protection features? The new language is a major change from the last edition of the code, contrary to how it was presented to the committee and the membership, it allows a means of egress path where you might be traveling down into the smoke and/or heat, and it is in conflict with long recognized protection features for atriums, i.e, unenclosed holes in floor/ceiling assemblies, Cost Impact: The code change proposal will increase the cost of construction E-Davidson.doc Public Hearing Results Committee Action: Disapproved Committee Reason: Section , Exception 4 is a long standing allowance in the code. No technical or anecdotal information was provided to indicate that this allowance is a safety issue. Removal of this exception would take out the option of the opening as well as the stairway. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1161

126 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Robert J Davidson, Davidson Code Concepts, LLC, representing self, requests Approval as Submitted. Commenter s Reason: The committee reason indicated that Section , Exception 4 is a long standing allowance in the code. No technical or anecdotal information was provided to indicate that this allowance is a safety issue. This is not factual, the use of stairways that are part of the means of egress, (in this case exit access stairways), was not permitted by the previous code. The code change that provided this language was testified to as editorial. It can t be editorial if it wasn t previously allowed. In this case language was improperly slipped into the code during the last cycle and when it gets identified the committee faults the person that identifies the sleight of hand for not having technical data to support the fix. Does this make sense? What about the lack of technical justification for the so called editorial changes that occurred? Totally ignored by the committee in discussion during the hearing and in the reason statement is the fact that based upon current code language if you connect 3 or more floors with one of these stairways you have an atrium that requires the installation of all of the fire protection features found in Section The fact that the code already has such requirements for atriums documents the safety issue the committee claims was not indicated.

Exception: Encroachments complying with Section (IFC [B] ) Wheelchair spaces at stairway landings. Where wheelchair spaces are located on the stairway landing in accordance with Section , the wheelchair space shall not be located in the required width or depth of the landing and doors shall not swing over the wheelchair spaces. Reason: The intent of this proposal is to clarify stairway landing requirements. These provisions are not intended to be applicable to the unique configurations required within assembly seating areas. Those are addressed in Section This proposal separates the component requirements of this section, allows a more precise understanding needed for both design and enforcement of required width and depth and provides a needed minimum landing depth requirement. In addition it provides a new requirement for landing shape that has previously been left to interpretation with needed explanation only offered within the code commentaries. Landing Width: It is not uncommon that the widths of the flights vary within a stairway and the widths of different stairways sharing the same landing at a common floor level also vary. In fact different stairway widths may be required as passenger loads increase in the direction of egress. The current language is ambiguous as it does not clearly state what The width is when there is more than one stairway width or flight width at a landing. Landing Depth is as critical as tread depth: Just as critical to good stairway design as tread depth is the depth of the landing. Landings should be designed to allow enough space to turn. Likewise and as the turning diminishes the landing should be of sufficient depth to prevent over stepping. Currently the code confuses landing depth as an element of its width without a specific depth requirement. The only specific reference to landing depth within this section serves to establish a need not exceed dimension of 48 inches (36 inches residential) for stairways with a straight run. Landing depth is especially critical at stairway landings that turn less than 90 degrees. Landing turns that are greater than 90 degrees are not addressed in this proposal because sufficient landing depth is provided by nature of the geometry. The intent of this proposal is not to increase the depth required at landings by the most common interpretations of the current code but to provide a clear application of the concept of landing depth at 2012 ICC FINAL ACTION AGENDA 1164

129 the walkline as experienced by the user. This proposal clarifies the current rectilinear requirements and provides a design solution that works regardless of the shape of the landing. The Walkline can be used to regulate landing Depth: In order to regulate landing depth at the walkline, Walkline, has been modified to include landings. The modification recognizes that the walkline has both straight elements that are parallel and curved elements that are concentric and relates the walkline to both winders and landings. The walkline is referenced in a new landing depth section and a relationship is provided for controlling the depth of a landing where flights meet. The measuring criteria for landing depth is congruous with the criteria for measuring tread depth as found in Riser height and tread depth. As illustrated in Figures 1-10 this proposal requires the landing depth increase as the angle of the turn diminishes to prevent overstepping of the landing and allow the space required to negotiate the turn. This correlates with the 48 inch need not to exceed depth of landings specified for stairways with straight runs currently in the code. Figure 1 and 6 shows a minimal 90 degree landing as built in accordance with the code. The landing in figure 1 has the minimum dimension necessary to provide for the continuous handrail connection as required in Handrail extensions. The minimum landing currently possible has a depth at the walkline as shown of 21 inches and is the minimum allowed by this proposal for a landing turn of 90 degrees. Since the code currently has a need not exceed limit of 48 inches applicable to the condition where the stairway is straight run a simple linear relationship between these two conditions allows for calculation of the data in Table 1 increasing the landing depth by a constant increment as the turning decreases. Figures 2-5 clearly illustrate examples from the table. Figure 6 shows a typical residential landing and figures 7-10 again illustrate examples from the table and the incremental increase needed for both spiral stairways and residential applications. It should be noted that this proposal further provides a viable landing depth whether or not the adjoining flights are curved as it is related to the degree of turning only at the landing of the stairway. Minimum Landing Depth: If the landing depth, determined from the table, exceeds the minimum stairway width then the minimum stairway width shall be the minimum landing depth. If the stairway width exceeds the landing depth from the table then the landing depth from the table is the minimum landing depth ICC FINAL ACTION AGENDA 1165

130 Spiral stairways and stairways with in dwelling units: Figures 5-10 illustrate the landing conditions for stairways within dwelling units and spiral stairways and coordinates closely with the 2012 IRC. It allows a smaller 90 degree value of 18 inches where section Handrail Extensions does not apply and correlates the incremental increase in depth with the minimum depth of 36 inches for residential stairways with a straight run. Particularly in residential applications this proposal helps to define the difference between a landing and a winder. Landing Shape: The shape of landings is not regulated in the code and is sometimes interpreted to permit only rectangular shapes. Clearly landings take different shapes dependent upon the angle at which flights meet. The unused outside corner of landings that is beyond the width measured perpendicular to the direction of travel is not needed for egress. Although this is explained in the ICC commentaries this proposal incorporates a new section titled landing shape to provide for consistent interpretation and enforcement. Doors and Wheelchair Space at Landings: The language for obstructions has been updated to reference The requirements are the same, but the new language would be consistent with text in aisle, corridors and exit passageways. The language for wheelchair spaces is existing. Cost Impact: This will not affect the cost of construction E-Coooper.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The proposal provides technical criteria for stairway landings of unusual shape which are currently not addressed in the code. However, it is not clear how the Table can be used for angles between the specific angles specified or how a designer would measure the angle of a stairway. Since the understanding of the table really needs the graphics provided in the reason for clarification, perhaps this could be considered as alternative means and covered in the commentary. Some of the language deleted from deals with means of egress width and accessibility requirements. This should not be lost. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: David W. Cooper, Stair Manufacturing and Design Consultants, representing Stairway Manufacturers Association, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Walkline. The walkline across winder treads and landings shall be parallel to the direction of travel and concentric through the turn. The walkline shall be located 12 inches (305 mm) from the side where the winders are narrower or from the side of shortest distance through the turn at a landing. The 12-inch (305 mm) dimension shall be measured from the widest point of the clear width at the walking surface. If winders are adjacent adjoining within the flight, the point of the widest clear stair width at the walking surface of the adjacent adjoining winders shall be used (IFC [B] ) Stairway landings. There shall be a floor or landing at the top and bottom of each flight of stairs. Exception: Aisle stairs complying with Section (IFC [B] ) Stairway landing width. The minimum width of landings shall be not less than the required width of the stairway. Every landing shall have a width at the top and bottom of each flight no less than the width of the flight at the junction with the landing. The minimum width of a landing at any point shall be not less than the width of the narrowest flight served as measured perpendicular to the walkline (IFC [B] ) Stairway landing depth. At landings of straight run stairways landings having no landing turn measuring 0 degrees and at stairway landing turns of less than 90 degrees or less between adjoining flights, the minimum landing depth shall be 44 inches (1118 mm) minus 1¼ inches (31.8 mm) for each 5 degrees increment of turn at the landing up to 90 degrees as not less than the smallest of the minimum landing width or the value from Table Landing shall be measured between the vertical planes of the foremost projection of the tread and landing nosings at the intersections with the walkline. Landing turns of 90 degrees shall have a minimum of depth of 21½ inches (546 mm) at the walkline ICC FINAL ACTION AGENDA 1166

131 Exception: Spiral stairways and stairways within dwelling and sleeping units shall have a minimum landing depth of 36 inches (914 mm) minus 1 inch (25.4 mm) for each 5 degrees increment of turn at the landing up to 90 degrees as measured between the vertical planes of the foremost projection of the tread and landing nosings at the intersections with the walkline. Landing turns of 90 degrees shall have a minimum of depth of 18 inches (457 mm) at the walkline. Table (IFC [B] Table ) Landing Depth (Delete table in its entirety.) (IFC [B] ) Stairway landing shape. Walls and guards at the The sides of landings at adjoining walls and guards shall be permitted allowed to be curved or segmented (IFC [B] ) Obstructions at stairway landings. The required width and depth of landings shall be unobstructed. Exception: Encroachments complying with Section (IFC [B] ) Wheelchair spaces at stairway landings. When wheelchair spaces are located on the stairway landing in accordance with Section , the wheelchair space shall not be located in the required width or depth of the landing and doors shall not swing over the wheelchair spaces. Commenter s Reason: The modification preserves the committee s interest in addressing the technical criteria for landings that is not currently addressed in the code. In particular the distinction between width and depth the depth of landings at the walkline the depth of landings at both curved and angular flights that meet at a landing the periphery shape of landings are addressed based on current minimum depths allowed The table that confused the committee has been removed and substituted with simple arithmetic that results in the landing depth dimension. Part of the confusion noted by the committee was that the data in the table was rounded and thereby misrepresented. A corrected table is shown here to clarify that the increments are equal and lineal and comply with the calculations made from the modified code text. The drawings submitted with the original proposal are no longer needed to understand the code text which now stands alone. By qualifying that landings of straight run stairs have 0 degrees of turn the needed clarification the committee requested for ease of use has been provided. Changes in the walkline section correct a submission error by substituting parallel text from the previous sentence and offering the more specific term adjoining to replace the somewhat subjective term adjacent. The essential requirements related to egress width and accessibility that the committee noted as deleted and critical, were in fact not eliminated but appeared on the next page of the monologue, simply relocated in new sections , and Section provides an updated reference to The requirements are the same, but the new language would be consistent with text in aisle, corridors and exit passageways. The language in for wheelchair spaces is intact, simply relocated to This is a much needed change that will address many issues that are inconsistently interpreted and often require reference to the commentary or other resources not in common use by designers, contractors, or enforcing officials. The committee recognized this and their other stated concerns have all been addressed in this modification. This change allows us to consistently regulate landing depth with the same fundamentals as tread depth and relate it clearly to the users walkline on the stairway regardless of the stairway plan-configuration. It is based on those requirements already understood in the code and does not change them but simply fills in the blanks that have been missing answers and left to interpretation. Your thorough consideration and approval as modified will be greatly appreciated by all that use the code. E91-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1167

132 E (IFC [B] ) Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: (IFC [B] ) Solid Risers. Risers shall be solid. Exceptions: 1. Solid risers are not required for stairways that serve as the means of egress from areas exempted from accessibility in accordance with Section that are not required to comply with Section , provided that the opening between treads does not permit the passage of a sphere with a diameter of 4 inches (102 mm). 2. Solid risers are not required within Type B or non-accessible dwelling or sleeping units. 3. Means of egress stairways shall be permitted to have openings between treads that do not permit the passage of a sphere with a diameter of 4 inches (102 mm). 24. Solid risers are not required for occupancies in Group I-3 or in Group F, H and S occupancies other than areas accessible to the public. There are no restrictions on the size of the opening in the riser. 35. Solid risers are not required for spiral stairways constructed in accordance with Section Solid risers are not required for alternating tread devices constructed in accordance with Section Reason: The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. The intent of this proposal is coordination with ADA requirements for solid risers on stairways as well as provide for a more logical and consistent application of solid risers. The 1991 ADA only scoped stairways that connected levels that did not have an accessible route. The 2010 ADA Standard scopes stairways that are part of a means of egress, not just stairways that are part of an accessible means of egress. Therefore, the current Section , Exception 1 was not coordinated with either the 1991 or 2010 ADA stairway provisions. If an area is not required to be accessible, the route to that space is also exempted from ADA requirements; therefore, means of egress stairways from these areas are not covered by ADA. IBC Section has similar exceptions for accessible areas. For example, exempts areas raised for purposes of life safety, fire safety or security. With the proposed revisions in Section , exception 1, stairways serving these areas are not required to have solid risers. The new exception 2 would allow open risers on stairways within dwelling units or sleeping units that were covered by ADA (i.e., Accessible units or Type A units). Open risers are a common with stairways that provide access to basements within a residence. One of the reasons for providing closed risers is to limit the chance that a cane could catch between risers. The 4 maximum opening would limit this as well as meet the 4 opening limits currently in the code for child protection. Current exception 2 (new exception 4) has the last sentence deleted. This text is not needed, plus it could lead code users to think that other exceptions had size limitations. Cost Impact: None E-BALDASSARRA-CTC.docx 2012 ICC FINAL ACTION AGENDA 1168

133 Public Hearing Results Committee Action: Disapproved Committee Reason: Application of Exception #3 is too broad. The proponent asked for disapproval so that CTC and the proponent of E95 can work together to clarify what openings are permitted. Section of the 2010 ADA Standard for Accessible Design does specify solid risers. The intent is to clarify which size opening should be permitted and still have the risers perform as if they were solid. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Carl Baldassarra, Code Technologies Committee, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Solid Risers Riser Opening Limitations. Risers shall be solid not have openings that allow passage of a sphere ½ inches (12.7 mm) in diameter. Exceptions: 1. Solid risers are not required for stairways that serve as the means of egress from areas exempted from accessibility in accordance with Section Solid risers are not required Risers within Type B or non-accessible dwelling or sleeping units not required to be Accessible or Type A units, provided that the openings between the lower adjacent tread, floor, or landing and the lower edge of the riser that do not allow permit the passage of a sphere with a diameter of 4 inches (102 mm) in diameter. 3. Means of egress stairways shall be permitted to have openings between the lower adjacent tread, floor, or landing and the lower edge of the riser that do not permit the passage of a sphere with a diameter of 4 inches (102 mm). 42. Solid risers are not required Risers for occupancies in Group I-3 or in Group F, H and S occupancies other than in areas not accessible to the public shall have no opening limitation. 53. Solid risers are not required Risers for spiral stairways constructed in accordance with Section shall have no opening limitation. 64. Solid risers are not required Risers for alternating tread devices constructed in accordance with Section shall have no opening limitation. 75. Solid risers are not required Risers for ship ladders constructed in accordance with Section shall have no opening limitation. Commenter s Reason: The intent of this public comment is coordination with ADA intent for solid risers but acknowledging what types of openings should be permitted. Generally, most stairways will have risers with a maximum opening size of ½ inch. Within residential units (other than Accessible or Type A units) stairways shall be permitted tread with a 4 inch opening similar to the guard requirements. Solid treads are not required in jails or not public areas in factories and storage for safety reasons. Solid risers would not allow adequate foot placement on the treads for spiral stairways, alternating tread devices or ships ladders. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as Areas of Study. The Area of Study for this code change and public comment is called IBC Coordination with the new ADAAG. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website Since its inception in April, 2005, the CTC has held twenty-four meetings all open to the public. In addition to holding face-to-face meetings, the CTC established Study Groups where any interested party can participate in conference calls on specific subjects such as this area of study without having to attend the face-to-face meetings.

134 E , (IFC [B] , ) Proposed Change as Submitted Proponent: David W. Cooper / Stairway Manufacturing and Design Consultants / Representing: Stairway Manufacturers Association (sma@stairways.org) Revise as follows: (IFC [B] ) (IFC [B] ) Solid Risers. Risers shall be solid. Exceptions: 1. Solid risers are not required for stairways that serve as the means of egress from areas exempted from accessibility in accordance with Section are not required to comply with Section , 2. Solid risers are not required within Type B or non-accessible dwelling or sleeping units provided that the openings between the lower adjacent tread, floor, or landing and the lower edge of the riser that do not permit the passage of a sphere with a diameter of 4 inches (102 mm). 3. Means of egress stairways shall be permitted to have openings between the lower adjacent tread, floor, or landing and the lower edge of the riser that do provided that the opening between treads does not permit the passage of a sphere with a diameter of 4 inches (102 mm). 24. Solid risers are not required for occupancies in Group I-3 or in Group F, H and S occupancies other than areas accessible to the public. There are no restrictions on the size of the opening in the riser. 35. Solid risers are not required for spiral stairways constructed in accordance with Section Solid risers are not required for alternating tread devices constructed in accordance with Section Solid risers are not required for ship ladders constructed in accordance with Section (IFC [B] ) Nosing and riser profile. The radius of curvature at the leading edge of the tread shall be not greater than 9/16 inch (14.3 mm). Beveling of nosings shall not exceed 9/16 inch (14.3 mm). Risers shall be solid and vertical or sloped under the tread above from the underside of the nosing above at an angle not more than 30 degrees (0.52 rad) from the vertical (IFC [B] ) Nosing projection size. The leading edge (nosings) of treads shall project not more than 1 ¼ inches (32 mm) beyond the tread below (IFC [B] ) Nosing projection uniformity. All nosing projections of the leading edges shall be of uniform size, including the projections of the nosings leading edge of the floor at the top of a flight. (Renumber subsequent sections) Reason: Section Nosing and riser profile is a constant source of controversy and misunderstanding. The reference to solid risers does not belong in the section that describes the profile or outline of a step. Notably masked in exception 1 by double negatives is the requirement for the limitation of openings in risers. This proposal clarifies the scoping for use of solid risers and coordinates with the new ADA guidelines as outlined by the CTC. Solid risers, as a new and separate section subsection of Treads and risers will appear prior to Nosing and riser profile. This allows easier identification of the opening limitation between treads and adjoining floors or landings that was previously misunderstood or not found. Exceptions 2 and 3 are similar to the CTC s proposal but assures that an opening limitation applies to Type B units as well as egress stairs and also provides that if an opening is used in the riser, it is in the lower portion of the riser 2012 ICC FINAL ACTION AGENDA 1170

135 height, as shown in Figure 1, allowing design options that may provide additional heal clearance in descent and the appropriate design of tread nosings compliant with ADA guidelines that are important in ascent. It is worth noting that the stairs covered in exception 2 would likely be means of egress stairs and would be covered by exception 3. If the committee wishes to modify this proposal by eliminating exception 2 in its entirety it would seem to work as well with less verbiage. The out of place reference to solid risers has been eliminated from Nosing and riser profile. The profile of a stair nosing and riser are aptly described without the misplaced reference to the composition of risers. The content of the exceptions has been moved from Nosing and riser profile to the new section and coordinated with ADA guidelines. Exception 7 adds ship ladders that were not previously included but should be as their use is made safer with the additional space for overhang of the toes in both ascent and in the typical backing down descent common to ladder use. Cost Impact: This will not affect the cost of construction #2-E-Cooper.doc Public Hearing Results Committee Action: Disapproved Committee Reason: While the committee agreed that the proponents of E94 and E95 should work together regarding coordination with openings in stairway risers and ADA, they felt that the addition of ships ladders in section was valid. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment 1: David W. Cooper, Stair Manufacturing and Design Consultants, representing Stairway Manufacturers Association, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Solid Risers Riser Opening Limitations. Risers shall be solid. Openings in risers between the walking surface of the adjacent tread, floor, or landing below and the lower edge of the riser above shall not allow passage of a sphere 2½ inches (63.5 mm) in diameter. Openings in risers 2-1/2 inches (63.5 mm) or higher above the walking surface of the adjacent tread, floor or landing below shall not allow the passage of a sphere ½ inch (12.7 mm) in diameter ICC FINAL ACTION AGENDA 1171

Solid risers are not required for stairways that serve as the means of egress from areas exempted from accessibility in accordance with Section Other than within Accessible and Type A dwelling and sleeping units, in Group R-3 occupancies; within dwelling and sleeping units in Group R-2 occupancies; and in Group U occupancies that are accessory to a Group R-3 occupancy or accessory to individual dwelling and sleeping units in Group R-2 occupancies; opening in risers shall not allow Solid risers are not required within Type B or non-accessible dwelling or sleeping units provided that the openings between the lower adjacent tread, floor, or landing and the lower edge of the riser that do not permit the passage of a sphere with a diameter of 4 inches (102 mm) in diameter through the allowed opening. 3. Means of egress stairways shall be permitted to have openings between the lower adjacent tread, floor, or landing and the lower edge of the riser that do not permit the passage of a sphere with a diameter of 4 inches (102 mm). 42. Solid risers are not required Risers for occupancies in Group I-3 or in Group F, H and S occupancies other than areas accessible to the public shall have no opening limitation. 53. Solid risers are not required Risers for spiral stairways constructed in accordance with Section shall have no opening limitation. 64. Solid risers are not required Risers for alternating tread devices constructed in accordance with Section shall have no opening limitation. 75. Solid risers are not required Risers for ship ladders constructed in accordance with Section shall have no opening limitation. (Portions of proposal not shown remain unchanged) Commenter s Reason: This modification preserves the intents of the original proposal but better clarifies the requirements and exceptions while making needed changes to coordinate with the 2010 ADA Standard. After working with the CTC to coordinate with the ADA Standard we saw no substantiation to support only a ½ sphere rule limitation, and further find that it would represent a substantial safety hazard where the removal of snow and debris on stairs is an issue. The title clearly reflects that the issue is to limit the openings in risers. Both the A117.1 and 2010 ADA standards require that Risers shall not be open but does not require solid risers. Limitation of the openings in risers should be the requirement. The 2½ inches opening in the lower portion of the riser serves to restrict penetration of canes and crutches and allows for removal of snow and ice accumulations that foreshorten the tread depth and stair width causing safety issues for all, especially crutch and cane users who by nature take a wider stance with their supportive mobility aid. White canes are typically used at an angle of approximately 40 degrees or more from the horizontal to detect the bottom riser of a flight on approach. White canes are not used in this manner on stairs. Once the step is detected, the cane is folded or held vertical and the stair is ascended without the use of the cane at an angle that would allow penetration of the riser. Supportive crutches and canes follow the user from behind on ascent and lead in descent to prevent pole vaulting making the riser inaccessible to the tip and lower extension of the mobility aid because it is in a near vertical position or at an opposing angle. The standards already provide a sphere rule limitation of ½ inch in treads to provide the needed surface to support the tips of supportive mobility aids. Such limitation is not required in the riser surface but should be allowed to provide for commonly used expanded metal or mesh products. The original exceptions one and three have been eliminated to coordinate with the new 2010 ADA standard. The original exception two has been modified to clarify the limited residential applications where a larger sphere rule in the bottom portion of the riser is acceptable and provide for compliance by allowing needed freedom of design. The remaining exceptions have been modified to more clearly emphasize that no limits apply to the openings in the risers in each of the cited applications. Public Comment 2: Glenn Mathewson, representing North American Deck and Railing Association, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Solid Risers opening limitations. Risers shall be solid. Openings in risers between the walking surface of the adjacent tread or landing below and the lower edge of the riser above shall not permit the passage of a sphere 4 inches (102 mm) in diameter. Exceptions 1. Solid risers are not required for stairways that serve as the means of egress from areas exempted from accessibility in accordance with Section Solid risers are not required within Type B or non-accessible dwelling or sleeping units provided that the openings between the lower adjacent tread, floor, or landing and the lower edge of the riser that do not permit the passage of a sphere with a diameter of 4 inches (102 mm). 3. Means of egress stairways shall be permitted to have openings between the lower adjacent tread, floor, or landing and the lower edge of the riser that do not permit the passage of a sphere with a diameter of 4 inches (102 mm). 41. Solid risers are not required for occupancies Openings shall not be limited in Group I-3, or in Group F, H and S occupancies other than in areas not accessible to the public. There are no restrictions on the size of the opening in the riser ICC FINAL ACTION AGENDA 1172

137 52. Solid risers are not required for Openings shall not be limited on spiral stairways, constructed in accordance with Section Solid risers are not required for alternating tread devices, constructed in accordance with Section Solid risers are not required for and ship ladders constructed in accordance with Section (Portions of proposal not shown remain unchanged) Commenter s Reason: The proposed section title is more appropriate for the nature of the subject and is consistent language with Section Opening Limitations (for guards). In regions with snowfall, solid risers will collect compacted snow in the inside corner created between a solid riser and a tread. Snow is pushed into the corner by the toe or heel of stair users. The compacted snow may form into ice and remain for extended periods, ultimately shortening the length of the tread depth. The use of partially open risers allows the snow to be pushed through the riser, and creates an inherently safer stairway to all users, regardless of the maintenance practices of snow removal. The committee did not provide any comment in their disapproval regarding the intent of the proposed modifications in E94 and E95, and rather seemed concerned about the language. Therefore, the modifications in this public comment are designed to streamline the text of both proposals, while providing an equivalent intent. The language of Section is unnecessarily complicated and the exceptions essentially become the rule. The inclusion of exception #3 in both E94 and E95 regarding means of egress stairways allows partially open risers in every stairway, and thus becomes the general provision. It is unnecessary to specify the other IRC sections related to spiral stairways and alternating tread devices, as these are IBCdefined terms. By definition, if you are dealing with one of these stairway types, you will always have to comply with the provisions of their specific IBC sections. This is unrelated to their unrestricted riser openings in this section. Ships ladders are not defined, and thus the reference to their respective chapter is appropriate.

138 E (IFC [B] ) Proposed Change as Submitted Proponent: David W. Cooper, Stairway Manufacturing and Design Consultants representing Stairway Manufacturers Association Revise as follows: (IFC [B] ) Vertical Total rise. A flight of stairs shall not have a total vertical rise greater than 12 feet (3658 mm) 147 inches (3734 mm) between floor levels or landings. Exceptions: 1. Aisle stairs complying with Section Alternating tread devices used as a means of egress shall not have a rise greater than 20 feet (6096 mm) between floor levels or landings. 3. Spiral stairways used as a means of egress from technical production areas. (Renumber subsequent sections) Reason: This section has been renamed to use the term Total rise that is common to the industry however the adjective vertical remains within the requirement for clear definition by all. The use of industry terms has been substantiated throughout the code. The elevation of 147 inches is a multiple of the maximum riser heights of, 7 inches (178 mm) commercial and 7-3/4 inches (197 mm) residential, allowed for IBC stairways. (See Table 1) This minor change of just 3 inches (76 mm) in the total rise of the flight would in many cases eliminate the cost of incorporating a landing and the space required, in many instances reducing costs of construction. As can be seen in the table below this change would require no additional steps in the stair than the current code requires and a change in riser height of just 5/32 inch (4 mm) or less when the minimum number of risers is desired. This represents no discernable difference consequential to the user. Figure 1 Residential Range = 7.58 (193mm) 7.74 (197mm), Commercial Range = 6.84 (174mm) 7 (178mm) see Table 1 Please note that the described circled ranges have been added to figures 1&2 by the proponent for the purpose of explanation ICC FINAL ACTION AGENDA 1174

139 Figure 2 Residential Range = 7.58 (193mm) 7.74 (197mm), Commercial Range = 6.84 (174mm) 7 (178mm) see Table 1 Please note that the described circled ranges have been added to figures 1&2 by the proponent for the purpose of explanation. Most Occupancies Dwelling Units Change in Riser Height inches Change in Riser Height mm Vertical Rise # Risers Riser Height Inches Riser Height mm Table 1 Testing in support of this proposal, as shown in the data presentations (Figure 1 and 2) from; The Influence of Rise and Going Combinations on Stair Safety by M S Roys, June 2004, 7th World Conference on Injury Prevention and Safety Promotion, Vienna 1, the minor variation in rise does not produce any consequential effect that can be noticed by users when comparing riser heights within the range in question. Please note that the circled ranges have been added to figure 1 & 2 by the proponent for the purpose of explanation. Figures one and two can be related to the perceived energy required in ascent as described by the subjective rating of the steepness of the stair and the need to pull oneself up the stair using the handrail. In these figures the user s ratings are on a scale of 1-7 and color coded. The visual display of the data shows little difference in the users ratings over the range in question. Additional testing data from this same study further illustrates little difference in the user s perception of riser height. When asked to rate descent of the stairway in response to the statement I felt safe when walking down the stair the risers heights of 6.69 inches, 7.09 inches, 7.48 inches (170 mm, 180 mm, 190 mm) all were rated the same with a tread depth of inches (275 mm). Compared with the same tread depth the riser heights of 7.87 inches, 6.30 inches (200 mm, 160 mm) were within approximately 0.5 points on a scale of 7 points further indicating little difference being perceived by the users. This provides further validation that the change proposed is reasonable and will not affect stair safety. Relocation of Section Vertical Rise is the first consideration and arguably most significant factor in determining the design of a stairway. It is of consequence to the number of treads and landings affecting width, headroom, and step geometry. This section is buried in the code and the fact that it is overlooked is of consequence. This proposal moves the section to head the stairway geometry requirements to assimilate the sequence of use in design ICC FINAL ACTION AGENDA 1175

140 Construction cost reduction It is common for the total rise to exceed 144 inches (3658 mm) with oversight of the requirement or minor changes in floor systems and finish flooring options. This requires the addition of an intermediate landing. Adding a landing increases the footprint of the stairway and the cost if the space is available. Understanding and Compliance This change will not increase the number of risers needed in the stairway or make the stairway less safe, or add any significantly perceived increase in energy to climb the stairway. This needed change provides a direct relationship between the vertical rise requirement and the requirements for riser height that would assure better understanding and compliance. Bibliography: 1.

Roys, 7 th World Conference on Injury Prevention and Safety Promotion, Vienna, June 2004 Cost Impact: This will reduce the cost of construction E-Cooper.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The committee recognized that with the suggested 147 maximum run that the number of risers would not increase within the run; and the new height is an allowance for using 7 inches for all risers within the run. However, the committee felt that the data presented should include if the injury rate would be different with this increased stairway run. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: David W. Cooper, Stair Manufacturing and Design Consultants, representing Stairway Manufacturers Association, requests Approval as Submitted. Commenter s Reason: The committee s concern for increased injury is unfounded. Injury data is not available. The NEISS does not categorize stair accident data regarding stair dimensions. The conclusive data presented from the study of persons using stairs of various dimensions shows that the users experience does not change within the range of this possible minor increase in riser height using the same number of risers as is currently allowed. The increase is less than 5/32 of an inch. The risers of the stair would not exceed the allowed limitations of maximum riser height of 7 inches public and 7 ¾ residential. This is a reasonable change adding only 3 inches to the allowed total rise of a stairway based on current research and testing done long since the legacy of 144 inches was adopted. This needed change will be of consequence in reducing the cost of construction by eliminating the additional space for the landing that is currently required and simplification of structural support of flights separated by a landing. It not only shortens the overall span of the stairway, it serves to decrease the distance the user needs to traverse. E98-12 Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1176

141 E (IFC [B] ) Proposed Change as Submitted Proponent: David W. Cooper, Stairway Manufacturing and Design Consultants representing Stairway Manufacturers Association Revise as follows: (IFC [B] ) Curved stairways. Curved stairways with winder treads shall have treads and risers in accordance with Section and the smallest radius shall not be less than twice 1.5 times the required width of the stairway. Exception: The radius restriction shall not apply to curved stairways for occupancies in Group R-3 and within individual dwelling units in occupancies in Group R-2. Reason: The current radius restriction of twice the radius has little basis other than a rule of thumb handed down from the legacy codes and causes unnecessary restriction of curved stairway design without enhancing the safety of the user. Reducing the smallest radius restriction to 1.5 times the width is a more reasonable standard that will allow greater freedom of design. See Figures 1-4 illustrating that only a slight increase in tread depth of less than 1¾ inches is realized at the outside radius and that the additional turning of the stairway does not substantially affect the view of other users that would be proximal on the stairway. The dimension used for the line of sight indicated by the diagonal lines drawn across the stairs is sixteen inches accommodating the required handrail and the proximal position of the stairway passenger. The position is based on the most common lateral displacement of 350 mm (13.8 inches) 1 from the center of the handrail to the center of the body for the handrail slope of 33º that is common to IBC compliant stairways. Added to this is half the allowed handrail width of 2¼ inches and the minimum clearance of 1½ inches totaling 16.4 inches ICC FINAL ACTION AGENDA 1177

142 The inconsequence of the minor increase in tread depth width is substantiated by testing performed by Mike Roys 2 as shown in Figure 5. Both the 15 inch (381 mm) and 16.7 inch (424 mm) tread depths lie in the same range of preference as indicated within the red circle. The circle was added by the proponent for the purpose of explanation. Bibliography Figure 5 1.

143 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: David W. Cooper, Stair Manufacturing and Design Consultants, representing Stairway Manufacturers Association, requests Approval as Submitted. Commenter s Reason: The committee failed to raise the question of increased egress time with the proponent during testimony yet cited it as their reason to disapprove. The supporting information provided shows that there is no change in the users experience traversing the slightly larger step realized at the outer most portion of the stair. The increase of only 1.7 inches would not require the user to take any additional steps in traverse of the stairway and would therefore, of its own, not increase the time of egress. Also related to egress speed is the range of visual perception both of the stairway and other users ahead on the stairway. The line of sight is clearly shown in figures 1 through 4 as not being changed in terms of the stairway segments in view at the tightest side of the turn. Finally the proposed change in the degree of turning required at each step is negligible if perceivable at all by the user. Recent WTC egress research shows a clear advantage to eliminating landing turns to speed stairway egress. Curved stairways offer a design alternative that allows for a continuous flow without sharp turns, and increased visual perception of the path ahead compared to multiple flights separated by landing turns. Curved stairways do not require the needed change of stride required to negotiate landings that causes significant backups in crowded egress situations. The legacy code is over restrictive. The proposed decrease in the minimum radius is reasonable, based on current research and testing and will not affect safe egress but rather offer greater flexibility in design.

144 E (IFC [B] ) Proposed Change as Submitted Proponent: John Williams, CBO, Chair, ICC Ad Hoc Committee on Health Care Revise as follows: (IFC [B] ) Power source. Exit signs shall be illuminated at all times. To ensure continued illumination for a duration of not less than 90 minutes in case of primary power loss, the sign illumination means shall be connected to an emergency power system provided from storage batteries, unit equipment or an on-site generator. The installation of the emergency power system shall be in accordance with Chapter 27. Exceptions: 1. Approved exit sign illumination means that provide continuous illumination independent of external power sources for a duration of not less than 90 minutes, in case of primary power loss, are not required to be connected to an emergency electrical system. 2. Group I-2 hospital exit sign illumination shall not be provided by unit equipment battery only. Reason: The IBC and IFC both have the same requirements. NFPA is less restrictive for UL listings of equipment. NFPA 70 is not referenced by IBC/IFC as does NFPA 99. IBC/IFC permit batteries. This proposal is submitted by the ICC Ad Hoc Committee for Healthcare (AHC). The AHC was established by the ICC Board of Directors to evaluate and assess contemporary code issues relating to hospitals and ambulatory healthcare facilities. The AHC is composed of building code officials, fire code officials, hospital facility engineers, and state healthcare enforcement representatives. The goals of the committee are to ensure that the ICC family of codes appropriately addresses the fire and life safety concerns of a highly specialized and rapidly evolving healthcare delivery system. This process is part of a joint effort between ICC and the American Society for Healthcare Engineering (ASHE), a subsidiary of the American Hospital Association, to eliminate duplication and conflicts in healthcare regulation. Since its inception in April, 2011, the AHC has held 5 open meetings and over 80 workgroup calls which included members of the AHC as well as any interested party to discuss and debate the proposed changes. All meeting materials and reports are posted on the AHC website at: E-WILLIAMS-ADHOC.doc Public Hearing Results Committee Action: Approved as Submitted Committee Reason: The requirement matches federal requirements for hospitals already in place and improves the reliability of the exit signage. The committee suggested that perhaps better wording would to require what the signage needed to be connected to rather than an exception for batteries. This might limit the mis-interpretation that remote batteries might be an option. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1180

145 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: John Williams, CBO, Chair, ICC Ad Hoc Committee on Health Care requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Power source. Exit signs shall be illuminated at all times. To ensure continued illumination for a duration of not less than 90 minutes in case of primary power loss, the sign illumination means shall be connected to an emergency power system provided from storage batteries, unit equipment or an on-site generator. The installation of the emergency power system shall be in accordance with Chapter 27. Exceptions: 1. Approved exit sign illumination means that provide continuous illumination independent of external power sources for a duration of not less than 90 minutes, in case of primary power loss, are not required to be connected to an emergency electrical system. 2. Group I-2 hospital Condition 2 exit sign illumination shall not be provided by unit equipment battery only. Commenter s Reason: Code change E103 is a technical change which proposes to revise the exception to note that exit sign illumination for hospitals is not to be provided by unit equipment batteries only. This was approved by the committee in Dallas. The purpose of this public comment is limited to the editorial coordination of terminology with the approval of Code change G257 (see below). In this case, hospitals are Group I-2 Condition 2. Since G257 deals only with terminology, this public comment is being submitted to E102 in order to focus the attention on the coordination of terminology issue. At the Code Development Hearing, the IBC - General committee approved as modified G which created two occupancy conditions for Group I-2, similar to what is currently in the IBC for Group I-3. The end result is that where warranted based on the type of occupancy, the code would designate Group I-2 hospitals as Group I-2 Condition 2. As indicated in the reason statement for G257, the benefit of the condition concept, when compared to creating new use groups, (i.e. Group I-5 or I-6) is that a majority of code requirements would still apply to all Group I-2 occupancies. Following the successful action on G257, the ICC Ad Hoc Committee for Healthcare (AHC) did a word search of the IBC along with a review of code changes submitted in the 2012 Cycle which are unique to hospitals and nursing homes to determine whether or not the condition designation was necessary in order to distinguish between the two typical Group I-2 occupancies hospitals (Condition 2) and nursing homes (Condition 1). As noted above, the majority of the code requirements do not differentiate based on these two types of Group I-2 and as such the number of instances where the Group I-2 condition designation is necessary is kept to a minimum. Code change E103 is one such application where the Group I-2 Condition 2 designation is warranted and therefore this public comment is being submitted by the AHC. The AHC was established by the ICC Board of Directors to evaluate and assess contemporary code issues relating to hospitals and ambulatory healthcare facilities. The AHC is composed of building code officials, fire code officials, hospital facility engineers, and state healthcare enforcement representatives.

146 E (IFC [B] ) Proposed Change as Submitted Proponent: Gene Boecker, AIA, Code Consultants, Inc, representing self Revise as follows: (IFC [B] ) Projections. On ramps, the clear width between handrails shall be 36 inches (914 mm) minimum. Projections into the required width of stairways and ramps at each side shall not exceed 41/2 inches (114 mm) at or below the handrail height. Projections into the required width shall not be limited above the minimum headroom height required in Section Projections due to intermediate handrails shall not constitute a reduction in the egress width provided that each intermediate handrail is not wider than 2-1/4 inches (57 mm). Reason: The intent, when this provision was originally added, was to allow intermediate handrails to not count against the required width since it was required on wide stairs and provided added safety on ramps. Because the prior code text was unclear what effect a handrail had on the allowed projections into the stair or ramp and what that did for the overall capacity of the egress element some change was necessary. When a person moves on a stair or ramp, using the handrail, the arm is over the railing. The person on the other side of the railing does likewise. This type of condition does not effectively reduce the capacity of the egress element and increases safety by virtue of the handrail itself. However, double railings widen the space between columns of people on ramps and stairs and can reduce capacity. A set of handrails separated by 10 inches may be helpful in providing each column with a handrail but it should be taken into consideration when calculating the capacity of the ramp or stair. The proposal uses a 2-1/4 inch dimension to allow for non-circular handrails which might meet the requirements of Section for Type I handrails. Thus, if a single railing (or multiple single railings) is placed within a stair or ramp, each railing, if less than 2-1/4 inches in width, would not count to decrease the capacity of the egress element or required width. However, if a set of double railings would be provided within the stair or ramp, the minimum overall width of a double railing would be 4 inches (two 1-1/4 inch railings, plus 1-1/2 inch clear between railings per Section and ). This would need to be deducted from the total width of the stair or ramp. Cost Impact: The code change proposal will not increase the cost of construction E-Boecker.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The proposed language could be interpreted to not allow a double handrail no matter how wide the stairway. This is needed for stairways with heavy traffic moving in two directions, such as schools during passing periods. The proponent should come back with a proposal that addresses limits for the typical double handrail. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Gene Boecker, AIA, Code Consultants, Inc (CCI), requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Projections. On ramps, the clear width between handrails shall be 36 inches (914 mm) minimum. Projections into the required width of stairways and ramps at each side shall not exceed 41/2 inches (114 mm) at or below the 2012 ICC FINAL ACTION AGENDA 1182

147 handrail height. Projections into the required width shall not be limited above the minimum headroom height required in Section Projections due to intermediate handrails shall not constitute a reduction in the egress width provided that each intermediate handrail is not wider than 2-1/4 inches (57 mm). Where a pair of intermediate handrails are provided within the stairway width without a walking surface between the pair of intermediate handrails and the distance between the pair of intermediate handrails is greater than 6 inches (152 mm), the available egress width shall be reduced by the distance between the closest edges of each such intermediate pair of handrails that is greater than six inches (152 mm). Commenter s Reason: The committee didn t think that the language was adequate for what to do when a pair of handrails is provided. The proposal addresses that by offering a method to calculate the egress width. The illustration shows in simple terms the dimension that must be deducted from the overall width of the stairway. Because handrails are allowed to protrude on the sides without reducing the egress width and a single intermediate handrail does not reduce the egress width, this solution is the simplest method for evaluating conditions where two handrails are provided without a walking surface between them. If the handrails touch one another then there is no reduction. However, because at least 1-1/2 inches must be provided for clearance around the handrail according to Section , the handrails must be at least 1-1/2 inches apart. In this configuration, no reduction is applied. If the handrails are 6 inches apart, and a thin barrier was provided at mid-point as a wall, the configuration would be like two stairways, side-by-side. On each side of the thin barrier, the handrail would be projecting 4-1/2 inches (half of six inches plus the 1-1/2 inch diameter railing) into the stair, exactly what is allowed by Section Therefore the maximum between handrails is 6 inches. If the pair of railings is located 12 inches apart, the stairway width available for egress would be reduced by 6 inches. For conditions where there is no walking surface between handrails, this is the maximum allowable separation between handrails without an egress capacity reduction. 6 max 4-1/2 max This methodology addresses the committee s concerns and recognizes that fact the intermediate handrails are capable of reducing the available width in stairways if designed in such a manner that it is not possible to walk on both sides of the handrails. ICC staff have indicated that there have been attempted designs with inches between handrails, based on the original language. This clearly infringes on the ability of the stair to convey the proper number of people to egress since it reduces the effective width. The proposal addresses that issue and also the concerns of the committee and other testifying, that the provisions recognize allowed protrusions.

148 E (IFC [B] ) Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: (IFC [B] ) Height. Required guards shall not be less than 42 inches (1067 mm) high, measured vertically as follows: 1. From the adjacent walking surfaces, 2. On the line connecting the leading edges of the tread nosings, and 3. On ramps from the ramp surface at the guard. 4. From a seatboard where a guard would be required at the walking surface and the seatboard is part of the guard or adjacent to the guard. Exceptions: 1. For one- and two- family dwellings and townhouses in Group R-2 and R-3, For occupancies in Group R-3 not more than three stories above grade in height and required guards within individual dwelling units and in areas serving the dwelling unit in occupancies in Group R-2 not more than three stories above grade in height with separate means of egress, required guards shall not be less than 36 inches (914 mm) in height measured vertically above the adjacent walking surfaces or fixed seating seatboard. 2. For Group R-2 and R-3 units, required guards within the dwelling unit shall not be less than 36 inches (914 mm) in height measured vertically above the adjacent walking surface or seatboard. 32. For occupancies in Group R-3, and within individual dwelling units in occupancies in Group R-2, guards on the open sides of stairs shall have a height not less than 34 inches (864 mm) measured vertically from a line connecting the leading edges of the treads. 43. For occupancies in Group R-3, and within individual dwelling units in occupancies in Group R-2, where the top of the guard also serves as a handrail on the open sides of stairs, the top of the guard shall not be less than 34 inches (864 mm) and not more than 38 inches (965 mm) measured vertically from a line connecting the leading edges of the treads. 54. The guard height in assembly seating areas shall comply with Section Along alternating tread devices and ship ladders, guards whose top rail also serves as a handrail, shall have height not less than 30 inches (762 mm) and not more than 34 inches (864 mm), measured vertically from the leading edge of the device tread nosing. Reason: The purpose of this change is to require higher guards when a fixed bench is part of or immediately adjacent to a guard. The concern is child safety for when children stand on a seat and possibly tip over the guard. The reference back to the floor surface in new Item 4 is to clarify where the measurement for the drop-off for where a guard is required is different from the measurement for the guard height. The changes to Exception 1 is to coordinate better with IRC. The guard height is permitted to be 36 both inside and outside the individual dwelling unit. Where a balcony or deck had a bench constructed as part of the guard, the guard height above the bench would be 36. New exception 2 is to allow a 36 high guard along an interior balcony or mezzanine within a Group R-2 multi-story apartment. This would allow guards and handrails along stairways (current exceptions 2 and 3) to not have a large change in elevation at the top landing to meet up with the guard. For these buildings, if there is an exterior balcony for a unit, the guard height would be 42 minimum. That would include measurement from a bench if it was constructed as part of the guard. The intent of this proposal is to coordinate with the proposal for perimeter guards along assembly seating being proposed by the ICC 300 Bleacher Safety Committee. It is not the intent for these provisions to apply to fixed assembly seating arrangements ICC FINAL ACTION AGENDA 1184

149 There types of facilities have issues of line-of-sight, requirements for handrails and guards along aisle that are stepped, ramped or level, crowd issues, etc. that are more appropriately handled in Section The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party.

Cost Impact: None E-Baldassarra-CTC.docx Public Hearing Results Committee Action: Disapproved Committee Reason: Seatboard is not defined in relation to this specific area. Seatboards are understood in bleachers, but requirements for guards in assembly seating areas are addressed in Section 1028 and ICC 300. If there is an understanding of what a seatboard might be, there is no indications of how close a seatboard has to be to be considered adjacent, and there no requirements for the seat to be fixed or not. A suggestion was requiring where the seatboard was within 36 inches horizontal of the falling hazard, similar to the guard requirements. Measuring the height for the guard from a different elevation (i.e., seatboard) other than the floor where the drop off is determined is confusing.

150 Commenter s Reason: The reason for disapproval of this change was due to the term seatboard being undefined. This modification mirrors the approved text from the IRC (Section R ) in an effort to both clarify the terminology and to achieve consistency with the IRC. The IRC does not use the term seatboard but rather fixed seating. The public comment retains the 42 guard height (IRC is 36 ) and the IBC exceptions are retained, with the change from seatboard to fixed seating, as the IBC scope is different than that of the IRC. In addition, there seemed to be some confusion at the Code Development Hearings regarding this being applied to assembly seating. Guards for assembly seating are clearly regulated by Exception 5 which requires compliance with Section Similarly, concerns were noted at the hearing with the term adjacent as it may be viewed as interpretive. A word search of the term adjacent in the IBC uncovered that it is used 219 times in the IBC. The picture below clearly illustrates the hazard to children falling over the guard where the adjacent fixed seating becomes a walking surface for a child. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as Areas of Study. The Area of Study for this code change and public comment is called Climbable Guards.

151 E (New) [IFC [B] (New)] Proposed Change as Submitted Proponent: Brad Emerick, P.E., City and County of Denver Fire Prevention representing the Fire Marshals Association of Colorado (FMAC) Add new text as follows: (IBC [F] ) Paths of egress travel. From the terminus of the common path of egress travel, two separate and distinct paths shall be provided that diverge at a minimum rate of 7 feet for every 10 feet of travel along the paths. Divergence shall continue until one of the following is attained: 1. The paths are separated by a distance equal to the separation required by Section , or 2. An exit access doorway or exit is reached by one of the paths. Exception: Where a building is equipped throughout with an automatic sprinkler system in accordance with Section or , the divergence rate shall not be less than 5 feet for every 10 feet traveled along the paths until Item 1 or 2 above is attained. Reason: The only place in the code requiring two separate and distinct paths is in a definition. Though it s not always possible, in general, requirements should be in the body of the code. In addition, the letter of the code allows the two separate and distinct paths required in the definition of Common Path of Egress Travel to parallel each other (even converge as long as they do not merge) with no minimum separation distance. The only criteria are that the paths be separate and distinct which are not defined. Because no minimum separation is established, the primary intent of two paths (i.e., that a single incident cannot block both) is repeatedly contested. Previous proposals to codify the concept that these paths be divergent were voted down in part because a fixed separation could not be applied at the point where the Common Path of Egress Travel terminates (terminus). The proposed section attempts to address these by establishing a minimum divergence rate in the body of the code based on distance traversed from the terminus of the common path. An exception is proposed that is consistent with the reduced exit or exit access separation permitted for a sprinklered building (i.e., sprinklered ~ 2/3 non-sprinklered). Though the divergence rates of 45 degrees (non-sprinklered) and 30 degrees (sprinklered) were in the original draft of this proposal, the rates of 7 feet per 10 feet of travel (approximately a 42 degree angle) and 5 feet per 10 feet of travel (approximately a 29 degree angle) are expressed in a way that is easier to verify on drawings and in the field. The figure below depicts a common path of travel coming in from the lower right, and the two rates of divergence (sprinklered and non-sprinklered) from its terminus. The straight lines with arrows represent the envelopes established by the proposed divergence rates. To keep the number of lines on the drawing to a minimum, both rates are measured from a common horizontal line. The squiggly red lines outside the non-sprinklered divergence rate represent actual travel paths and attempt to illustrate that in a non-sprinklered building, these paths may converge as long as they do not cross the envelope established by the minimum divergence rate of 7 feet for every 10 feet of travel. The sprinklered divergence rate is depicted for comparison ICC FINAL ACTION AGENDA 1187

152 Cost Impact: This code change proposal will not increase the cost of construction (new)-E-Emerick.doc Public Hearing Results Committee Action: Disapproved Committee Reason: This is an overly complex solution to a problem that may not exist. In addition, it may conflict with other provisions in the code such as the stairway separation of 30 feet permitted in high rise buildings and allowances for protected paths of travel. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Brad Emerick, PE, Denver Fire Department Fire Prevention Division, representing Fire Marshal s Association of Colorado (FMAC), requests Approval as Submitted. Commenter s Reason: The Means of Egress (MOE) is a pedestrian path through a building to a safe location outside the building. The code regulates the width, change in elevation, obstacles, length, protection level, etc., of this path. Initially, only a single path is required from any point in a building (the common path of egress travel or CPT). If at the CPT terminus, occupants traveling on the CPT have not reached an exit or exit discharge, then they are to be provided separate and distinct access to two exits or exit access doorways (previously two separate and distinct paths to two exits ). This segment of the MOE path between the end of the CPT and the exit access doorway or exit is the only portion not regulated clearly by the code ICC FINAL ACTION AGENDA 1188

153 The intent is to have the two paths diverge at some minimum rate in order to preclude a single event from blocking both. Mandating the paths separate at 180 is not reasonable but neither is permitting the paths to parallel each other with only a bodywidth separation (which is permitted by the letter of the code). Every divergence rate in between is open to the interpretation of separate and distinct which fosters inconsistency. Several designs have been proposed in our jurisdiction where the two paths parallel each other 6 to 10 feet apart and unfortunately one was permitted on appeal. On that particular application two exits were separated by 1/3 the diagonal dimension of the area served but were both located along a 10-foot wide hallway extending away from the dining area. The CPT ended prior to all occupants reaching the first exit but occupants had to pass by the first exit to reach the second. Though the paths were parallel, because they were separated by about 10 feet, they were deemed separate and distinct (citing the letter of the code). In reality this configuration is just an extension the CPT and violates the intent of the code. This proposal would establish minimum, reasonable divergence rates for the two paths required from the end of the CPT. Two rates are proposed that are consistent with the exit or exit access separation permitted for sprinklered and non-sprinklered buildings. Under this proposal, the paths are only required to diverge until they are separated by a distance equal to the separation required for exit access doorways or exits, or until one of the paths reaches an exit access doorway or exit whichever occurs first. Though the divergence rates of 45 degrees (non-sprinklered) and 30 degrees (sprinklered) were originally contemplated for this proposal, the rates of 7 feet per 10 feet of travel (an approximately 42 degree angle) and 5 feet per 10 feet of travel (an approximately 29 degree angle) are expressed in a way that is easier to verify on drawings and in the field.

154 E Table (IFC [B] Table ) Proposed Change as Submitted Proponent: Thomas S. Zaremba, Roetzel & Andress, Glazing Industry Code Committee ( GICC ) and Primary Fire Rated Glazing Manufacturers (tzaremba@ralaw.com) Revise as follows: TABLE (IFC [B] TABLE ) CORRIDOR FIRE-RESISTANCE RATING REQUIRED FIRE-RESISTANCE RATING (hours) c OCCUPANT LOAD SERVED Without sprinkler With sprinkler system OCCUPANCY BY CORRIDOR system H-1, H-2, H-3 All Not permitted 1 H-4, H-5 Greater than 30 Not permitted 1 A, B, E, F, M, S, U Greater than E Greater than R Greater than 10 Not permitted 0.5 I-2 a All Not permitted 0 I-1, I-3 All Not permitted 1 b Reason: According to a June 2011 NFPA Research Report: U.S. fire departments responded to an estimated average of 6,260 structure fires in educational properties in , annually. These fires caused annual averages of 85 civilian fire injuries and $112 million in direct property damage. The majority of fires and losses in educational properties were in nursery through high schools. Source: Evarts, Structure Fires in Educational Properties, NFPA Fire Analysis and Research Division (June 2011); emphasis added. Day Care Centers averaged 590 structure fires; 8 injuries; and $4.5 Million in direct property damage annually while K-12 educational facilities averaged an annual 4510 structure fires; 68 injuries; and $95 Million in direct property damage. Source: Evarts, Structure Fires in Educational Properties, NFPA Fire Analysis and Research Division (June 2011). Most educational facilities built since the late 1970s are required to have automatic sprinkler and other fire/smoke alarm systems which, according to FEMA, likely explains why no deaths from school structure fires were reported in As displayed in the 2002 FEMA Table below, fires in educational facilities were generally less damaging than non-residential fires; however, it is important to note that fires in schools were generally more injurious than other non-residential structure fires. LOSS MEASURES FOR SCHOOL STRUCTURE FIRES (2002) Loss Measure All Non-Residential Structure Fires School Structure Fires $ Loss/Fire $21,505 $15,956 Injuries/1,000 Fires Fatalities/1,000 Fires Source: FEMA, Topical Fire Research Series, School Fires, Vol. 4, Issue 6 (December 2004); emphasis added. Clearly, the documented number of fires, injuries and the extensive damage done annually to educational occupancies, warrants increased fire protection for students, teachers, property and fire service members entering the buildings after fires are reported, either to rescue students that may be missing from the evacuation count, or to just put out the fires. In the past, the principal impediment to adopting added fire protection features has been the increased cost of construction. However, SSOE Group, a world-wide architectural firm with extensive experience in the design of educational occupancies, recently completed a study of the costs associated with adding fire rated exit corridors to schools with automatic sprinkler systems. SSOE took the actual costs of three different schools that it had actually designed recently with automatic sprinkler systems and determined the additional costs necessary to fire rate their exit corridors in accordance with the 2009 edition of the IBC. SSOE used three different schools as the basis for its report. The first is a 69,200 sq.ft. elementary school. The second is a 175,502 sq.ft. middle school. The third is a 401,797 sq.ft. high school ICC FINAL ACTION AGENDA 1190

155 SSOE s summary comparing the costs to install automatic sprinkler systems to the costs of fire rating the exit corridors in these schools is set out below. From SSOE s summary, it is clear that adding fire rated corridors actually costs less than it does to install automatic sprinkler systems. COST SUMMARY Elementary school Middle School High School Total Building Cost less equipment $10,427, $18,929, $42,851, Automatic sprinkler systems Initial cost $188, $367, $643, Maintenance over life cycle $5, $5, $5, Fire protection totals $194, $373, $648, Fire rated exit corridors Initial commissioning cost $1, $4, $7, FRJS $38, $107, $174, Costs for door upgrades $15, $17, $55, Pv of Annual inspection costs $10, $25, $33, Cost difference for fire rated glazing $83, $115, $121, Duct penetrations $16, $24, $41, Other penetrations $5, $14, $23, PV of Additional penetrations over life cycle $1, $4, $4, Fire rated exit corridor totals $174, $313, $461, Fire rated corridor costs as a percentage of Automatic Sprinkler System 89.69% 84.09% 71.14% Fire rated corridor costs as a percentage of Total Building Costs 1.67% 1.66% 1.08% Adding fire rated exit corridors to E-occupancies will result in inherently safer school buildings at less cost than including automatic sprinkler systems. Moreover, according to the SSOE report, the added cost of adding fire rated corridors represents less than 2% of the total cost to build these schools or only: % of the total $ million cost to build the 69,200 sq. ft. elementary school; % of the total $ million cost to build the 172, 502 sq. ft. middle school; and % of the total $ million cost to build the 401,797 sq. ft. high school. Finally, the base schools used in the SSOE were built with an expected life of fifty (50) years. When the costs of adding fire rated corridors are amortized over the 50 year anticipated life of these school buildings, the added cost is absolutely nominal. As to those schools affected by the proposal, it would add compartmentalization and provide redundant life safety and fire protection features to E-occupancies to the same level of fire protection that is currently required in a number of I-occupancies 2012 ICC FINAL ACTION AGENDA 1191

156 (including assisted living facilities, congregate care facilities, halfway houses and social rehabilitation facilities). If adopted, this proposal would affect only E-occupancies (including day care centers) that are greater than 12,000 sq. ft. in size. E-occupancies are a special case. They involve children. Fire and life safety protections should be redundant in E- occupancies, especially given the large number of fires experienced annually; the large number of injuries related to fires that are experienced annually; the large dollar losses experienced annually from fires in school properties; and the small overall cost to add fire rated corridors. As the number of students served by our school systems increases with increasingly smaller adult-to-student ratios, the small added cost of construction should not be any impediment to the increased level of protection that this proposal would provide our children, their teachers and the fire service. We urge the Committee to support this proposal. Bibliography: 1. Evarts, Structure Fires in Educational Properties, NFPA Fire Analysis and Research Division (June 2011). 2.

Cost Impact: This proposal will increase the cost of construction. T E-Zaremba.doc Public Hearing Results Committee Action: Disapproved Committee Reason: Correlation between a 1 hour rated corridor and a reduction in fire loss has not been provided. Fire data provided showed that current school design has one of the best safety records for life and property. Another concern raised was the situation of lock downs during an attach event within the school. Lock downs can be for dangerous situations outside the school. No data has been provided to indicate how a rated corridors will protect against an internal attack. To build for a combined sprinkler failure, lock down situation and fire attack scenario is too restrictive for everyday design. The increase in cost would not just be walls, but would also include fire rated doors, fire dampers, etc., therefore adding this requirement would be a significant increase in cost without sufficient justification. In addition, school administration now often requires teachers to keep door open for visual communication with the classrooms. Teachers and students use classroom doors continually during passing periods. Closers, as required on fire doors, would be a conflict with both situations. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment : Thomas S. Zaremba, Roetzel & Andress, representing Glazing Industry Code Committee and Primary Fire Rated Glazing Manufacturers; and Robert J Davidson, Davidson Code Concepts, LLC, representing self; requests Approval as Submitted. Commenter s Reason (Zaremba): The question posed by this code change is whether sprinklered E-occupancies should also have rated exit corridors? The Committee disapproved it. Proponents are asking the membership to revisit this question and adopt E as submitted. E presents documented evidence that: Educational properties sustained an estimated annual average of 6,260 structure fires between 2005 and During that time period, these school fires caused annual averages of 85 injuries and $112 million in direct property damage. Day care facilities averaged 590 structure fires, 8 injuries and $4.5 million in direct property damage annually. K-12 educational facilities sustained an annual average of 4,510 structure fires, 68 injuries and $95 million in direct property damage. In 2002, on average, school structural fires resulted in 22 injuries per 1,000 fires, significantly higher than the 14.4 injuries sustained per 1,000 fires in non-residential structure fires ICC FINAL ACTION AGENDA 1192

157 In disapproving the proposal, the Committee misinterpreted this data. In its reason statement, the Committee concluded that this [f]ire data showed that current school design has one of the best safety records for life and property. In fact, however, the data shows that: there are a very large number of school structural fires annually, school structural fires have a significantly higher number of injuries per 1,000 fires than other non-residential occupancies, and school fires cause millions of dollars in property damage every year. The Committee also said that adopting E would represent a significant increase in cost without sufficient justification. Proponents will address increased cost and justification for E separately below. Respecting cost, Proponents of E submitted detailed information from a Report prepared by SSOE (an architectural firm operating world wide) to provide the Committee, and now the Membership, with accurate information as to the additional costs necessary to add fire rated corridors to three different types and sizes of sprinklered school buildings. First, the cost data for the three schools presented with E are actual costs. SSOE was able to use actual costs because it actually designed the three sprinklered schools it used in its Report. The first school was a 69,200 sq. ft. elementary. The second was a 175,502 sq. ft. middle school and the third was a 401,797 sq. ft. high school. Second, it should be noted that, in its reason statement, the Committee said that [t]he increase in cost would not just be walls, but would also include fire rated doors, fire dampers, etc., suggesting that Proponents had presented data that only included the added costs of fire rating the corridor walls. The Committee misunderstood the data that was presented because it clearly included all costs necessary to completely fire rate the exit corridors of all three schools, including their walls, doors, windows, fire dampers, etc. Significantly, The SSOE report concluded that the added cost to fire rate the exit corridors of these schools was actually less than the costs actually incurred to install automatic sprinkler systems. In that regard, adding rated corridors would cost approximately 8% less than it cost to install sprinklers in the smallest of the three schools (the elementary school); 15% less than it cost to install sprinklers in the middle school; and 29% less than it cost to install sprinklers in the high school. More importantly, the SSOE Report concluded that adding fire rated exit corridors would only add: 1.6% (or $174,355.50) to the $ million actual cost to build the 69,200 sq. ft. elementary school, 1.6% (or $313,784.53) to the $ million actual cost to build the 172,502 sq. ft. middle school, and 1.08% (or $461,552.48) to the $ million actual cost to build the 401,797 sq. ft. high school. SSOE designed each of these school buildings to have a useful life of fifty or more years. When the relatively small added cost to fire rate the exit corridors is amortized over the useful lives of these buildings, that additional $4,000 to $10,000 per year cost can only be considered nominal. Even though adding fire rated corridors would add only 1.6%, or less, to the total costs of these buildings, the question remains: Are these cost increases, no matter how small, justified? To answer that question, it is safe to assume that no safety system can ever be considered foolproof or infallible. This premise can be found in a 1998 code change proposal that was submitted during the process of drafting the ICC. There, two Fire Prevention Officers representing the California Fire Chief s Association, proposed a change to the First Draft of the International Building Code (T ). In it, they proposed that corridors in Educational (and six other) occupancies should have a required fire resistance rating of 2 hours with or without sprinklers. In support of their proposal, they said that: In California, fire sprinkler systems fail. Safe egress for tenants through corridors cannot be solely dependent upon fire sprinkler systems. (Emphasis added.) From that premise, the analysis moves to a proposal submitted in 1999 by the legendary John G. Gus Degenkolb, a Los Angeles Battalion Chief and Fire Protection Engineer. He proposed a 0.5 hour rated corridor in E- (and six other) occupancies (E225-99). His rational was, simple: A corridor is defined as an enclosed exit access component that defines and provides a path of egress travel to an exit. Once in a corridor, movement is restricted to travel within the enclosing walls and along the length of the corridor until a door to another atmosphere is provided. As such, it should have some level of resistance to the transmission of smoke from the area adjacent to the corridor. His rational was not based solely on logic, but on actual fire tests that he and others conducted in a Los Angeles school building, less than a year after the deaths of 95 students and teachers in the Our Lady of the Angels School fire in Chicago, Illinois. The report of these tests are found in Operation School Burning, published by the National Fire Protection Agency (1959). Four findings from Operation School Burning are instructive in answering the question: Are cost increases related to adopting E justified? The first relevant finding from Operation School Burning is that smoke (specifically as it pertains to visibility and irritant effects) was the principal life safety hazard and that in the absence of automatic sprinklers untenable smoke conditions were reached in 2 to 7 minutes from the start of the fire on at least one entire floor above the fire. A second finding was that [w]ith a complete automatic sprinkler system, untenable smoke conditions were not reached in any corridors except two local areas closest to the test fire. A third finding was that: [W]hen the test fire was arranged so as to provide extensive shielding against sprinkler water distribution, untenable smoke conditions developed in the corridor of fire origin and those above. The fourth finding was that: Partial automatic sprinklers (sprinklers installed in corridors and stairways but not over the test fire) did not prevent smoke spread throughout the building even when installed to provide a water curtain between the test fire and the corridors. In the absence of redundancy, these findings suggest that if there is a sprinkler failure over the site of a fire in a school, whether due to a water supply failure, an obstruction in water distribution, or a simple sprinkler head failure, untenable smoke could pose a significant life safety hazard to students and teachers in a matter of minutes. Based on NFPA s U.S. Experience with Sprinklers by John R. Hall, Jr. (March 2012), we know that [s]prinklers operated in 91% of all reported structure fires large enough to activate sprinklers. When sprinklers operated, they were effective 96% of the time, resulting in a combined performance of operating effectively in 88% of all reported fires where sprinklers were present in the area and the fire was large enough to activate them ICC FINAL ACTION AGENDA 1193

158 Stated otherwise, for whatever reason, sprinklers may fail to operate effectively in 12% of the fires where sprinklers are present in the area and the fire is large enough to activate them. If a sprinkler fails in the area of a fire in one of the more than 6,000 school structure fires that history tells us are likely to occur annually in this country, then, according to Operation School Burning, in the absence of the redundancy of fire rated corridors, untenable smoke conditions may well be reached in a matter of minutes. Redundant safety systems in the form of automatic sprinklers and fire rated construction capable of containing the propagation of smoke and fire into exit corridors are both necessary to ensure the safety of our schools. Paraphrasing Gus Degenkolb, the exit corridors through which our students and teachers travel to reach a safe atmosphere should have some level of resistance to smoke or flame in areas adjacent to the corridor. Currently, if a school is sprinklered, exit corridors can be constructed from materials having no reliable ability to resist either smoke or flame. Proponents submit that the small increase in cost and slight inconvenience associated with fire rating the exit corridors of sprinklered Educational Occupancies is more than adequately justified by the inherently safer school buildings that will result from the adoption of E as submitted. Proponents urge you to support the adoption of E as submitted by voting against the standing motion to disapprove E and by voting in favor of a motion to adopt E as submitted. Commenter s Reason (Davidson): Correlation between a 1 hour rated corridor and a reduction in fire loss has not been provided. Fire data provided showed that current school design has one of the best safety records for life and property. Past fire data was based on old assumptions, i.e., when the fire alarm went off students immediately lined up and exited the building. Since the events at Columbine High School and other schools across the U.S. that have been subjected to violent events the operation of the schools has changed and now lock downs are routine, i.e., once a lock down is enacted classroom doors are locked and staff and students are under orders to ignore fire alarms since they may be used to generate vulnerable victims. So the parameters that the old trade-off for sprinkler protection has changed and is no longer relevant. If the code has any basis at all, when a safety parameter code language is based upon is eliminated, the code should be modified relative to that change. It is irresponsible to go forward relying on old data that is no longer relevant. Another concern raised was the situation of lock downs during an attach event within the school. Lock downs can be for dangerous situations outside the school. No data has been provided to indicate how a rated corridors will protect against an internal attack. To build for a combined sprinkler failure, lock down situation and fire attack scenario is too restrictive for everyday design. Correct, lock downs can be for events outside the school and guess what, the same lock down rules apply, lock your doors and ignore the fire alarm. Because of this there are many more chances of fire occurring during a lock down event. The protection concerning an interior attack is if a fire occurs at that time either accidentally or started by the actors committing the crime. The committee believing that we should not recognize the possibility of a lock down and fire occurring at the same time and the inability of the sprinkler system to handle the fire can only be done by ignoring factual testimony and a complete lack of knowledge of events that have already occurred. In the Columbine High School attack they had propane cylinders rigged to explode and cause a catastrophic fire, fortunately the failed to go off. Similar attacks discovered and stopped in the planning stages included similar plans. Even the recent attack in Aurora included an explosion and fire expectation in the apartment building. Do we need for one of these events to be successful before we recognize the need to change in response to changing societal norms? In addition, school administration now often requires teachers to keep door open for visual communication with the classrooms. I don t know where this statement arose from, but it is not factual. Classroom doors are typically kept shut to keep out the noise of someone in the hallway and to secure the classroom. Industry even markets locking systems specific to classrooms to lock them to the hallway side. School policy typically requires doors to be secured at the start of a class and kept secured throughout to eliminate ease of access by those that wish to harm teachers or students. The I-Codes have added requirements for lock down plans to be submitted to the fire code official and for fire alarm systems to utilize an emergency voice/alarm communication system to ensure there is a method to inform staff and students when to evacuate after they ignore the fire alarm. The final piece needed is to protect the egress corridor from the effects of a fire that may occur or be started by the actor. We protect prisoners in an I-3 with fire-resistance rated corridors, why would we not do that for our children as well? E Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1194

159 E , (IFC [B] , ) Proposed Change as Submitted Proponent: Steve Pfeiffer representing City of Seattle, Department of Planning & Development Revise as follows: (IFC [B] ) Location. Exterior egress balconies shall have a minimum fire separation distance of 10 feet (3048 mm) measured at right angles from the exterior edge of the egress balcony to: 1. Adjacent lot line lines; 2. Other portions of the building; and from 3. Other buildings on the same lot unless the adjacent building exterior walls and openings are protected in accordance with Section 705 based on fire separation distance (IFC [B] ) Location. Exterior exit stairways and ramps shall have a minimum fire separation distance of 10 feet (3048 mm) measured at right angles from the exterior edge of the stairway or ramp, including landings, to: 1. Adjacent lot line lines; 2. Other portions of the building; and from 3. Other buildings on the same lot unless the adjacent building exterior walls and openings are protected in accordance with Section 705 based on fire separation distance. Reason: The purpose of this change is to clarify that an exterior exit stairway or egress balcony needs a minimum 10 feet separation where a building wraps around on itself, such as a U-shaped building. The phrase at right angles was added because the definition of fire separation distance measures from a wall rather than the exterior edge. Cost Impact: The code change proposal will not increase the cost of construction E-Pfeiffer.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The proponent asked for additional time to reconsider some of the language in the proposal. There may be a concern with use of the term fire separation when dealing with a single building. Right angles may not be the correct way to measure protection at a curved wall.

160 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Steven Pfeiffer, City of Seattle, representing Department of Planning & Development, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Location. Exterior egress balconies shall have a minimum fire separation distance of 10 feet (3048 mm) measured at right angles from the exterior edge of the egress balcony to: 1. Adjacent lot lines; 2. Other portions of the building; 3. Other buildings on the same lot unless the adjacent building exterior walls and openings are protected in accordance with Section 705 based on fire separation distance. For the purpose of this section other portions of the building shall be treated as separate buildings (IFC [B] ) Location. Exterior exit stairways and ramps shall have a minimum fire separation distance of 10 feet (3048 mm) measured at right angles from the exterior edge of the stairway or ramp, including landings, to: 1. Adjacent lot lines; 2. Other portions of the building; 3. Other buildings on the same lot unless the adjacent building exterior walls and openings are protected in accordance with Section 705 based on fire separation distance. For the purpose of this section other portions of the building shall be treated as separate buildings. Commenter s Reason: This modification is proposed to clarify that an exterior exit stair or ramp, or exterior egress balcony always needs a minimum 10 feet separation, even where a building wraps around on itself, such as a U-shaped building. If both of a building s egress balconies or exterior stairways are within 10 feet of each other, a single fire could compromise both. The original proposal changed fire separation distance to separation distance which created a problem when measuring to the centerline of a street or alley. The original proposal would have not have allowed the separation between exterior balconies or stairways to be measured to the centerline of the street. This comment retains the provision that distance be measured at right angles because that provision is taken from the current definition of fire separation distance.

Where dwelling units are located on a story with other occupancies, the actual number of dwelling units divided by 4 plus the ratio from the other occupancy does not exceed one (IFC [B] ) Exits from specific space. Exits serving specific spaces or areas need not be accessed by the remainder of the story when all of the following are met: 1. The number of exits from the entire story complies with Section ; 2. The access to exits from each individual space in the story complies with Section ; and 3. All spaces within each portion of a story shall have access to the minimum number of approved independent exits based on the occupant load of that portion of the story but not less than two exits (IFC [B] ) Basements. A basement provided with one exit shall not be located more than one story below grade plane (IFC [B] ) Single-story or multi-story dwelling units. Individual single-story or multistory dwelling units shall be permitted to have a single exit within and from the dwelling unit provided that all of the following criteria are met: 1. The dwelling unit complies with Section as a space with one means of egress and 2. Either the exit from the dwelling unit discharges directly to the exterior at the level of exit 2012 ICC FINAL ACTION AGENDA 1199

Three exits, or exit access stairways or ramps providing access to exits at other stories, shall be provided from any story or occupied roof with an occupant load of 501-1,000. Four exits, or exit access stairways or ramps providing access to exits at other stories, shall be provided from any story or occupied roof with an occupant load greater than 1, (IFC [B] ) Additional exits. In buildings over 420 feet in height, additional exits shall be provided in accordance with Section (IFC [B] ) Exit configuration. Exits, or exit access stairways or ramps providing access to exits at other stories, shall be arranged in accordance with the provisions of Section through Exits shall be continuous from the point of entry into the exit to the exit discharge (IFC [B] ) Access to exits at adjacent levels. Access to exits at other levels shall be by stairways or ramps. Where access to exits occurs from adjacent building levels, the horizontal and vertical exit access travel distance to the closest exit shall not exceed that specified in Section Access to exits at other levels shall be from an adjacent story. Exception: Landing platforms or roof areas for helistops that are less than 60 feet ( mm) long, or less than 2,000 square feet (186 m 2 ) in area, shall be permitted to access the second exit by a fire escape, alternating tread device or ladder leading to the story or level below (IFC [B] ) Vehicular ramps. Vehicular ramps shall not be considered as an exit access ramp unless pedestrian facilities are provided. Reason: The intent of this proposal is to reorganize Section 1020 for clarity Separation for the 3 rd exit was deleted by E82-04/05 as too subjective, however, this language should be reinserted because now there is no language to describe where additional exits are located The word independent is added for clarity (no one should consider a double door as two exits). The minimum number of MOE have been moved into a table format for clarity and ease of reference for other requirements. The exceptions are not needed since the number required is based on exit and/or access to exits. Open parking and outdoor stadiums are exit access stairways from each floor above grade. New Table Requirements from and are relocated together into Table format. Allowances are extended to be number of exits and/or number of access to exits (i.e., exit access doorways, exit access stairways, exit access ramps) This section is revise for a positive where permitted approach rather than exceptions.

There was some concerns regarding the additional sentence in Section regarding separation for the third and fourth exits. While not a specific measurement, the added language that says not blocked should provide at least a limited indication of what would be an appropriate level of separation. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Ali M. Fattah P.E., representing City of San Diego Development Services Department, requests Approval as Modified by this Public Comment.

Commenter s Reason: The Means of Egress Committee approved this code change submitted by Colorado Consulting modifying the requirements for single exit buildings. We are concerned that table (1) does not address the case where multiple basement exist below a buildings and we believe that the table applies to a single basement below grade plane. We are also concerned that a residential building on a sloped site may have multiple basements and that grade and not grade plane should be the differentiating factor.

166 E (IFC [B] ) Proposed Change as Submitted Proponent: Philip Brazil, P.E., Senior Engineer, Reid Middleton, Inc., representing Washington Association of Building Officials, Technical Code Development Committee Revise as follows: (IFC [B] ) Exits from stories. Two exits, or exit access stairways or ramps providing access to exits, from any story or occupied roof shall be provided where one of the following conditions exists: 1. The occupant load or number of dwelling units exceeds one of the values in Table (1) or (2). 2. The exit access travel distance exceeds that specified in Table (1) or (2) as determined in accordance with the provisions of Section Helistop landing areas located on buildings or structures shall be provided with two exits, or exit access stairways or ramps providing access to exits. Exceptions: 1. Rooms, areas and spaces complying with Section with exits that discharge directly to the exterior at the level of exit discharge, are permitted to have one exit. 2. Group R-3 occupancy buildings shall be permitted to have one exit. 3. Parking garages where vehicles are mechanically parked shall be permitted to have one exit. 4. Air traffic control towers shall be provided with the minimum number of exits specified in Section Individual dwelling units in compliance with Section Group R-3 and R-4 congregate residences shall be permitted to have one exit Exits serving specific spaces or areas need not be accessed by the remainder of the story when all of the following are met: The number of exits from the entire story complies with Section ; The access to exits from each individual space in the story complies with Section ; and All spaces within each portion of a story shall have access to the minimum number of approved independent exits based on the occupant load of that portion of the story, but not less than two exits. Reason: Exception #6 was added by Proposal E5-09/10 but a reason for the exception was not given in the reason statement accompanying the proposal and there is no corresponding provision in the 2009 IBC. Note that the deletion has no effect on Group R-3 occupancies in that are permitted to have one exit by Exception #2.

167 Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment 1: Jonathan Siu, City of Seattle, Department of Planning & Development, representing Washington Association of Building Officials, Technical Code Development Committee, requests Approval as Modified by this Public Comment. Replace the proposal as follows: Exits from stories. Two exits, or exit access stairways or ramps providing access to exits, from any story or occupied roof shall be provided where one of the following conditions exists: 1. The occupant load or number of dwelling units exceeds one of the values in Table (1) or (2). 2. The exit access travel distance exceeds that specified in Table (1) or (2) as determined in accordance with the provisions of Section Helistop landing areas located on buildings or structures shall be provided with two exits, or exit access stairways or ramps providing access to exits. Exceptions: 1. Rooms, areas and spaces complying with Section with exits that discharge directly to the exterior at the level of exit discharge, are permitted to have one exit. 2. Group R-3 occupancy buildings shall be permitted to have one exit Parking garages where vehicles are mechanically parked shall be permitted to have one exit Air traffic control towers shall be provided with the minimum number of exits specified in Section Individual dwelling units in compliance with Section Group R-3 and R-4 congregate residences occupancies shall be permitted to have one exit Exits serving specific spaces or areas need not be accessed by the remainder of the story when all of the following are met: The number of exits from the entire story complies with Section ; The access to exits from each individual space in the story complies with Section ; and All spaces within each portion of a story shall have access to the minimum number of approved independent exits based on the occupant load of that portion of the story, but not less than two exits. Commenter s Reason: The intent of this proposal is to clean up the text that allows a single means of egress from R occupancies. While the Means of Egress Committee approved the original proposal as submitted, it has come to our attention there is a possibility the approved text is not consistent with the Fair Housing Act. Although there was no testimony to that effect in Dallas, we are submitting this public comment to head off the possibility of creating a conflict between the IBC and the Fair Housing Act. The question of consistency with the Fair Housing Act revolves around how R-4 occupancies are treated. Our understanding of the Act is R-4 occupancies cannot be treated differently than R-3 occupancies. By deleting the exception for single exits for R-4 congregate residences, it could be construed that the code is treating the two occupancies differently. However, congregate residences is not a term that is used in the IBC anymore, so referring to R-4 congregate residences does not make sense. All the uses listed in Section for an R-4 occupancy classification could be construed to be congregate residences. On the other hand, if the congregate care facilities in Section is thought to correspond with congregate residences, we do not see a justification for limiting the application of this section to just congregate care facilities all the uses listed in Section are of similar hazard, else they would be placed in a different occupancy (most likely an I occupancy). For those reasons, we have proposed reinserting the exception for R-4 s and to allow a single exit for all R-4 occupancies, not just congregate residences (whatever those are, in the context of the IBC). For R-3 occupancies, the intent of the original proposal was to delete redundant text that allows R-3 occupancies to have one exit both Exceptions 2 and 6 in the 2012 IBC allows this. Apparently, the Means of Egress Committee agreed with us that Exception 2 covered Exception 6. Since this public comment changes Exception 6 (now Exception 5 in the public comment) to apply to all R-3 occupancies, the intent of the original code change is still accomplished, but in a different way. In this case, Exception 2 is covered, and can be deleted ICC FINAL ACTION AGENDA 1203

168 Public Comment 2: Steve Thomas, CBO, Denver, CO, representing self; Wayne Jewell, CBO, CPCA, Green-Oak, MI, representing self; request Approval as Submitted by this Public Comment Replace the proposal as follows: (IFC [B] ) Exits from stories. Two exits, or exit access stairways or ramps providing access to exits, from any story or occupied roof shall be provided where one of the following conditions exists: 1. The occupant load or number of dwelling units exceeds one of the values in Table (1) or (2). 2. The exit access travel distance exceeds that specified in Table (1) or (2) as determined in accordance with the provisions of Section Helistop landing areas located on buildings or structures shall be provided with two exits, or exit access stairways or ramps providing access to exits. Exceptions: 1. Rooms, areas and spaces complying with Section with exits that discharge directly to the exterior at the level of exit discharge, are permitted to have one exit. 2. Group R-3 occupancy buildings shall be permitted to have one exit. 3. Parking garages where vehicles are mechanically parked shall be permitted to have one exit. 4. Air traffic control towers shall be provided with the minimum number of exits specified in Section Individual dwelling units in compliance with Section Group R-3 congregate living facilities and R-4 congregate residences facilities shall be permitted to have one exit. 7. Exits serving specific spaces or areas need not be accessed by the remainder of the story when all of the following are met: 7.1. The number of exits from the entire story complies with Section ; 7.2. The access to exits from each individual space in the story complies with Section ; and 7.3. All spaces within each portion of a story shall have access to the minimum number of approved independent exits based on the occupant load of that portion of the story, but not less than two exits (IFC [B] ) Exit access stairways. Floor openings between stories created by exit access stairways shall be enclosed. Exceptions: 1. In other than Group I-2 and I-3 occupancies, exit access stairways that serve, or atmospherically communicate between, only two stories are not required to be enclosed. 2. Exit access stairways serving and contained within a single residential dwelling unit or sleeping unit in Group R-1, R- 2 or R-3 occupancies are not required to be enclosed. 3. Exit access stairways serving and contained within a Group R-3 congregate living facility or a Group R-4, facility are not required to be enclosed. (No changes to remainder of section not shown. Renumber exceptions 3 through 10.) (IFC [B] ) Common path of egress travel. The common path of egress travel shall not exceed the common path of egress travel distances in Table TABLE (IFC TABLE [B] ) COMMON PATH OF EGRESS TRAVEL OCCUPANCY WITHOUT SPRINKLER SYSTEM (feet) WITH SPRINKLER Occupant Load SYSTEM (feet) 30 > 30 R-3, R-4 e b (No change to portions of table not shown) For SI: 1 foot = mm. a.

The length of a common path of egress travel in a Group R-3 occupancy located in a mixed occupancy building or Group R-3 or R-4 within a congregate living facility. f. For the distance limitations in Group I-2, see Section ICC FINAL ACTION AGENDA 1204

169 Commenter s Reason: As stated in the proponents reason, Section , Exception 6 was added as part of E5-09/10. The intent of this proposal is to have a complete package for the exit stairway requirements for congregate living facilities in Groups R-3 and R- 4, as an alternative to deleting the allowance for one exit staairway in Section , Exception 6. Exception 2 to Section is for the building of Group R-3, which would typically be a one- or two-family dwelling unit. Exception 6 is for Group R-3 and R-4 occupancies includes congregate living facilities with 16 or fewer residents; by definition a congregate living facility can be a part of a building. A congregate living facility is defined as sleeping units with shared kitchen and bathing facilities, so these are not dwelling units. The number of occupants in these occupancies is very limited and the occupants are familiar with their surroundings. This provision allows the same standards of design as required for single family homes to be applied to these types of facilities, keeping the code in-line with the requirements of the Federal Fair Housing provisions. While the original proposal chose to delete the allowance for a single stairway within these small congregate residences, this proposal s addition to Sections and attempts to coordinate the requirements for open stairways and travel distance to address these types of facilities.

170 E (IFC [B] ) Proposed Change as Submitted Proponent: Steve Pfeiffer representing City of Seattle, Department of Planning & Development Revise as follows: (IFC [B] ) Mixed occupancies. Where one exit, or exit access stairway or ramp providing access to exits at other stories, is permitted to serve individual stories, mixed occupancies shall be permitted to be served by single exits provided each individual occupancy complies with the applicable requirements of Table (1) or Table (2) for that occupancy. Where applicable, cumulative occupant loads from adjacent occupancies shall be considered in accordance with the provisions of Section In each story of a mixed occupancy building, the maximum number of occupants served by a single exit shall be such that the sum of the ratios of the calculated number of occupants of the space divided by the allowable number of occupants for each occupancy does not exceed one. In each story containing both Group R-2 dwelling units and other occupancies, the maximum number of dwelling units and occupants served by a single exit shall be such that the sum of the ratios of the actual number of dwelling units divided by 4, plus the calculated number of occupants of the rest of the story, divided by the allowable number of occupants for each occupancy, does not exceed one. Reason: This change allows use of the unity formula when a story contains both dwelling units and some other occupancy. For example, a second story would be permitted to be served by a single exit if it contained one dwelling unit and an office with an occupant of 21 or fewer (1/4 + 21/29 = ). Or, a second story could contain three dwellings and an office with an occupant load of 7 or fewer, yet still be served by a single exit (3/4 + 7/29 = ). The first paragraph of this section requires each occupancy to comply with the travel distance requirements in the table. Cost Impact: The code change proposal will not increase the cost of construction E-Pfeiffer.doc Public Hearing Results Committee Action: Disapproved Committee Reason The proposed formula is difficult to understand. In E127, the last sentence in Section addresses this issue. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1206

171 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Rick Lupton, City of Seattle representing Dept. of Planning & Development, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Mixed occupancies. Where one exit, or exit access stairway or ramp providing access to exits at other stories, is permitted to serve individual stories, mixed occupancies shall be permitted to be served by single exits provided each individual occupancy complies with the applicable requirements of Table (1) or Table (2) for that occupancy. Where applicable, cumulative occupant loads from adjacent occupancies shall be considered in accordance with the provisions of Section In each story of a mixed occupancy building, the maximum number of occupants served by a single exit shall be such that the sum of the ratios of the calculated number of occupants of the space divided by the allowable number of occupants for each occupancy does not exceed one. Where dwelling units are located on a story with other occupancies, the actual number of dwelling units divided by 4 plus the ratio from the other occupancy does not exceed one. In each story containing both Group R-2 dwelling units and other occupancies, the maximum number of dwelling units and occupants served by a single exit shall be such that the sum of the ratios of the actual number of dwelling units divided by 4, plus the calculated number of occupants of the rest of the story, divided by the allowable number of occupants for each occupancy, does not exceed one. Commenter s Reason: If E127 does not pass then this code change is still necessary to address what to do when dwelling units are mixed with another occupancy and applying the unity formula. The original proposal has been modified to incorporate more understandable language proposed in E127, addressing the committee s concern. If E127 passes at the Final Action Hearing then the proposal will be withdrawn. E Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1207

Interior exit stairways and interior exit ramps serving as an exit component in a means of egress system shall comply with the requirements of this section. Interior exit stairways and ramps shall be enclosed and lead directly to the exterior of the building or shall be extended to the exterior of the building with an extended exit passageway conforming to the requirements of Section 1023, except as permitted in Section An interior exit stairway or ramp shall not be used for any purpose other than as a means of egress.

Public Comment: Carl Baldassarra, Chair, Code Technologies Committee, requests Approval as Submitted. Commenter s Reason: This public comment is intended to correct an inadvertent error of omission with Item E7-12 that was approved as modified during the 2012 ICC code development hearings in Dallas, TX. E7-12 was intended to clarify and refine the provisions of Item E5-09/10 that was approved for inclusion in the 2012 IBC. E7-12 relocated the technical requirements for exit access stairways from Section to a new Section It also removed the provisions of Section applicable to interior exit stairways; however, failed to relocate them in Section It was not the intent of E-7 to remove the enclosure requirements for exit stairs from the code. The intent was to relocate the exit stair enclosure requirements to section This oversight was discovered during the discussion of Item E at the Dallas code development hearings. Passage of E will fix this error and maintain the clear requirement that exit stairs shall be enclosed. The following language is currently contained in Section of the 2012 IBC Interior exit stairways. Interior exit stairways shall lead directly to the exterior of the building or shall be extended to the exterior of the building with an exit passageway conforming to the requirements of Section 1023, except as permitted in Section Where required. Interior exit stairways shall be included, as necessary; to meet one or more means of egress design requirements, such as required number of exits or exit access travel distance Enclosure. All interior exit stairways shall be enclosed in accordance with the provisions of Section ICC FINAL ACTION AGENDA 1208

173 These inadvertently deleted provisions have been placed in proper technical context in Section Approval of this public comment will restore necessary charging language for the enclosure of interior exit stairways and ramps in the 2015 Edition of the IBC. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as Areas of Study. The Area of Study for this code change and public comment is called Unenclosed exit stairways.

174 E (IFC [B] ) Proposed Change as Submitted Proponent: Dennis Richardson, PE; Building Official, City of Salinas, representing Tri-Chapter (Peninsula, East Bay and Monterey Bay Chapters of ICC) Revise as follows: (IFC [B] ) Extension. Where interior exit stairways and ramps are extended to an exit discharge or a public way by an exit passageway, the interior exit stairway and ramp shall be separated from the exit passageway by a fire barrier constructed in accordance with Section 707 or a horizontal assembly constructed in accordance with Section 711, or both. The fire-resistance rating shall be at least equal to that required for the interior exit stairway and ramp. A fire door assembly complying with Section shall be installed in the fire barrier to provide a means of egress from the interior exit stairway and ramp to the exit passageway. Openings in the fire barrier other than the fire door assembly are prohibited. Penetrations of the fire barrier are prohibited. Exception Exceptions: 1. Penetrations of the fire barrier in accordance with Section shall be permitted. 2. Separation between an interior exit stairway or ramp and the exit passageway shall not be required if there are no openings or penetrations in the exit passageway. Reason: It is practice to utilize exit passageways and ramps as required to extend or connect the exit enclosure protection horizontally at building offsets and other obstructions until the stairway can then again proceed downward ultimately terminating at a discharge or being extended to the discharge. The purpose in having a door at this interface in the existing requirement is to prevent smoke from a possible open door or other penetration in the passageway from traveling up the exit enclosure. This is prevented if there are no openings or penetrations in the exit passageway. The exit passageway is constructed strictly as an extension of the enclosure at a horizontal offset. Egress can proceed faster if there are not intermediate doors contained at the enclosure transitions. Cost Impact: This code change will not increase the cost of construction E-Richardson.doc Public Hearing Results Committee Action: Disapproved Committee Reason: This proposed language is too restrictive for the exit passageway. It is not possible to build an exit passageway with no openings (i.e., lights, ventilation, sprinklers). Where interior exit stairways are connected by a passageway, a door should be provided for compartmentation of the exit path. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1210

175 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Dennis Richardson, PE, CBO, City of Salinas, representing Tri-Chapter (Peninsula, East Bay and Monterey Chapters, ICC), requests Approval as Modified by this Public Comment. Modify the proposal as follows: Extension. Where interior exit stairways and ramps are extended to an exit discharge or a public way by an exit passageway, the interior exit stairway and ramp shall be separated from the exit passageway by a fire barrier constructed in accordance with Section 707 or a horizontal assembly constructed in accordance with Section 711, or both. The fire-resistance rating shall be at least equal to that required for the interior exit stairway and ramp. A fire door assembly complying with Section shall be installed in the fire barrier to provide a means of egress from the interior exit stairway and ramp to the exit passageway. Openings in the fire barrier other than the fire door assembly are prohibited. Penetrations of the fire barrier are prohibited. Exceptions: 1. Penetrations of the fire barrier in accordance with Section shall be permitted. 2. Separation between an interior exit stairway or ramp and the exit passageway extension shall not be required if there are no openings or penetrations in the exit passageway extension. Commenter s Reason: The original proposed code change mistakenly included penetrations (along with openings) in exception 2 as prohibited from the exit passageway extension if no doors are provided. Members of the Egress Committee correctly pointed out that only openings would need to be prohibited in the passageway extension to obtain this exception and the original proposed exception was overly restrictive. This public comment has been revised accordingly. E Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1211

176 E (New); [IFC [B] (New)] Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Add new text as follows: (IFC [B] ) Elevator Lobby identification signs. At landings in interior exit stairways where two or more doors lead to the floor level, the door leading to the elevator lobby shall be identified by signage located on the door or directly adjacent to the door stating Elevator Lobby. Signage shall be in accordance with Section Items 4, 5 and 6. (Renumber subsequent sections) Reason: The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. This proposal is one of several proposals submitted by the CTC Elevator lobby SG. The ICC Executive Board directed the Code Technology Committee (CTC) to study the issue of elevator lobby separations in November 2010 due to the number of code change proposals submitted addressing this issue over a number of code change cycles. The Code Technology Committee formed a study group on the elevator lobby separation issue in December Note that this subject had been previously addressed by CABO/BCMC in 1986 with a similar conclusion. The code change proposals submitted are the result of the CTC s study of the issue. Note that the scope of the activity was as follows: Scope Review the need for elevator lobbies, with emphasis on building use, building and hoistway height, active and passive fire protection features associated with the aforementioned. Review the differences and specific needs when dealing with elevator lobbies of traditional-use elevators, fire service elevators, and occupant evacuation elevators. Review related code provisions, such as egress from and through elevator lobbies. Review the appropriate use of alternatives including pressurization of hoistways, additional doors, roll-down style barriers, and gasketing systems. Review with members of elevator industry to scope the requirements of applicable elevator reference standards as it deals with elevator lobby design, use and construction. Review design and construction requirements for elevator lobbies, including but not limited to dimensions, location and separation. Review applicable code change history, technical studies and loss statistics as part of this review. Based upon the extensive nature of this area of study, 5 Task Groups were formed during the process to provide in-depth review and to manage the number of issues. These task groups developed a number of proposals that were coordinated throughout the process. More information on this CTC area of study can be found at the following link. The focus is on necessary signage for entrance into elevator lobbies from interior exit stairway landings. This issue is more specific to Fire service access elevators and the potential for multiple required doors. The code currently requires direct access from the lobby to a stairway and additionally the same stairway must have a door that opens directly to the floor based upon standpipe access issues (i.e. limiting the number of doors that need to be open to lay hose during a fire). Fire fighters and occupants need to readily determine which door leads to the enclosed elevator lobby therefore signage is necessary to assist in wayfinding. The enclosed elevator lobby could be for fire service access elevators (FSAE) or occupant evacuation elevators. Since the signage need can apply to either type of enclosed elevator lobby and is related to interior exit stairways the requirements are proposed in Section See discussion on CTC elevator lobby proposal coordination in code change FS##-12 Cost impact: E-BALDASSARRA-CTC.docx 2012 ICC FINAL ACTION AGENDA 1212

177 Public Hearing Results Committee Action: Approved as Submitted Committee Reason: This signage is necessary for fire fighters when there is a fire service access elevator lobby. However, there could be some situations where there are two doors to the same level which do not have a fire service access elevator lobbies. There are also provisions that were approved by the General committee that would allow access to the fire service access elevator via a rated corridor. Additional revisions may be needed for further coordination.

Public Comment 1: Lee J Kranz, City of Bellevue Washington, representing WABO TCD, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Elevator Lobby identification signs. At landings in interior exit stairways where two or more doors lead to the floor level, the any door leading with direct access to the an enclosed fire service access or occupant evacuation elevator lobby shall be identified by signage located on the door or directly adjacent to the door stating Elevator Lobby. Signage shall be in accordance with Section Items 4, 5 and 6. Commenter s Reason: As stated in the original proposal s reason statement, these signs are needed to provide direction for firefighters and building occupants where more than one door is provided for access to a floor from an interior exit stairway. Although the Means of Egress Committee approved this proposal as submitted, they pointed out the text as proposed applies broadly to all elevator lobbies, as opposed to only those associated with fire service access or occupant evacuation elevators. In addition, the General Committee approved item G175-12, which provides exceptions to the requirement that fire service access and occupant evacuation elevator lobbies have direct access to an interior exit stairway. This public comment coordinates this item with G and responds to the Means of Egress Committee comments by limiting the requirement for providing signage to those doors that open directly into enclosed fire service access or occupant evacuation elevator lobbies. The term direct access is defined via G as a path of travel from a space to an immediately adjacent space through an opening in the common wall between the two spaces. For reference, the relevant approved-as-submitted text of G follows: G (Approved as Submitted) Revise as follows: Interior exit stairway access. The fire service access elevator lobby shall have direct access from the enclosed elevator lobby to an enclosure for an interior exit stairway. Exception: Access to an interior exit stairway shall be permitted to be through a protected path of travel that has a level of fire protection not less than the elevator lobby enclosure. The protected path shall be separated from the enclosed elevator lobby through an opening protected by a smoke and draft control assembly in accordance Section Interior exit stairway access. The occupant evacuation elevator lobby shall have direct access from the enclosed elevator lobby to an interior exit stairway or ramp.

178 Public Comment 2: Jonathan Siu, representing City of Seattle Dept of Planning & Development, requests Approval as Modified by this Public Comment. Modify the proposal as follows: (IFC [B] ) Elevator Lobby identification signs. At landings in interior exit stairways where two or more doors lead to the floor level, the any door leading with direct access to the an enclosed elevator lobby shall be identified by signage located on the door or directly adjacent to the door stating Elevator Lobby. Signage shall be in accordance with Section Items 4, 5 and 6. Commenter s Reason: As stated in the original proposal s reason statement, these signs are needed to provide direction for firefighters and building occupants where more than one door is provided for access to a floor from an interior exit stairway. In approving this proposal as submitted, the Means of Egress Committee pointed out the text as proposed applies broadly to all elevator lobbies, as opposed to only those associated with fire service access or occupant evacuation elevators. Our response is if the signs are being provided to prevent confusion, both for firefighters and building occupants who are in the stairs, then it is immaterial as to what kind of lobby the door opens into any extra doors are likely to cause confusion, and therefore, they should be provided with signs. The change in the text to require the signage only for doors providing direct access to an enclosed lobby is to coordinate this proposal with Item G175-12, which was approved as submitted by the General Committee. G provides exceptions to the requirement that fire service access and occupant evacuation elevator lobbies have direct access to an interior exit stairway. The result of this public comment is if the door does not provide direct access to an enclosed lobby, it is not required to have signage. For reference, the relevant approved-as-submitted text of G follows: G (Approved as Submitted) Revise as follows: Interior exit stairway access. The fire service access elevator lobby shall have direct access from the enclosed elevator lobby to an enclosure for an interior exit stairway.

179 E (IFC [B] ) Proposed Change as Submitted Proponent: Dennis Richardson, PE; Building Official, City of Salinas, representing Tri-Chapter (Peninsula, East Bay and Monterey Bay Chapters of ICC) Revise as follows: (IFC [B] ) Exterior stairway and ramp protection. Exterior exit stairways and ramps shall be separated from the interior of the building as required in Section Openings shall be limited to those necessary for egress from normally occupied spaces. Where a vertical projection of the planes of the guard of an exterior stairway or ramp including landings are exposed by other parts of the building at an angle of less than 180 degrees (3.14 rad), the exterior wall shall be rated in accordance with Section Exceptions: 1. Separation from the interior of the building is not required for occupancies, other than those in Group R-1 or R-2, in buildings that are no more than two stories above grade plane where a level of exit discharge serving such occupancies is the first story above grade plane. 2. Separation from the interior of the building is not required where the exterior stairway or ramp is served by an exterior ramp or balcony that connects two remote exterior stairways or other approved exits, with a perimeter that is not less than 50 percent open. To be considered open, the opening shall be a minimum of 50 percent of the height of the enclosing wall, with the top of the openings no less than 7 feet (2134 mm) above the top of the balcony. 3. Separation from the interior of the building is not required for an exterior stairway or ramp located in a building or structure that is permitted to have unenclosed exit access stairways in accordance with Section Separation from the interior of the building is not required for exterior stairways or ramps connected to open-ended corridors, provided that Items 4.1 through 4.5 are met: 4.1 The building, including corridors, stairways or ramps, shall be equipped throughout with an automatic sprinkler system in accordance with Section or The open-ended corridors comply with Section The open-ended corridors are connected on each end to an exterior exit ramp or stairway complying with Section The exterior walls and openings adjacent to the exterior exit stairway or ramp comply with Section At any location in an open-ended corridor where a change of direction exceeding 45 degrees (0.79 rad) occurs, a clear opening of not less than 35 square feet (3.3 m 2 ) or an exterior stairway or ramps shall be provided. Where clear openings are provided, they shall be located so as to minimize the accumulation of smoke or toxic gases.

181 E (IFC [B] ) Proposed Change as Submitted Proponent: Robert J Davidson, Davidson Code Concepts LLC, representing SaftiFirst a Division of O Keeffes, Inc. (rjd@davidsoncodeconcepts.com) Revise as follows: (IFC [B] ) General. Exits shall discharge directly to the exterior of the building. The exit discharge shall be at grade or shall provide direct access to grade. The exit discharge shall not reenter a building. The combined use of Exceptions 1 and 2 shall not exceed 50 percent of the number and capacity of the required exits. 1. A maximum of 50 percent of the number and capacity of interior exit stairways and ramps is permitted to egress through areas on the level of exit discharge provided all of the following are met: 1.1. Such enclosures egress to a free and unobstructed path of travel to an exterior exit door and such exit is readily visible and identifiable from the point of termination of the enclosure The entire area of the level of exit discharge is separated from areas below by construction conforming to the fire-resistance rating for the enclosure The egress path from the interior exit stairway and ramp on the level of exit discharge is protected throughout by an approved automatic sprinkler system. All portions of the level of exit discharge with access to the egress path shall either be protected throughout with an automatic sprinkler system installed in accordance with Section or , or separated from the egress path in accordance with the requirements for the enclosure of interior exit stairways or ramps. 2. A maximum of 50 percent of the number and capacity of the interior exit stairways and ramps is permitted to egress through a vestibule provided all of the following are met: 2.1. The entire area of the vestibule is separated from areas below by construction conforming to the fire-resistance rating for the enclosure The depth from the exterior of the building is not greater than 10 feet (3048 mm) and the length is not greater than 30 feet (9144 mm) The area is separated from the remainder of the level of exit discharge by construction providing 45 minutes of fire-resistance rated protection at least the equivalent of approved wired glass in steel frames The area is used only for means of egress and exits directly to the outside. 3. Horizontal exits complying with Section 1025 shall not be required to discharge directly to the exterior of the building. Reason: The purpose of this proposal is to eliminate a left over reference to wired glass for purposes of fire protection. The last few cycles references to wired glass have been replaced with references to fire-rated glazing or other generic terms to eliminate a reference to a specific product. The reference here is replaced with a requirement of 45 minutes of fire resistance because that is the level of fire-resistance rating historically associated with wired glass in steel frames and the code section is looking for that equivalent. From NFPA , Standard on Fire Test for Window and Glass Block Assemblies : B.2.3 The current requirements for fire test duration are open, whereas previous editions limited the duration to 45 minutes. With the advent of new glazing materials that provide various levels of fire protection, the current requirements have responded to the needs of the industry and the fire protection community by establishing various fire protection ratings that are both longer and shorter than the previous 45-minute specification. The 45-minute limit was based on the ability of standard wired glass to perform satisfactorily in accordance with earlier editions of NFPA 257. Cost Impact: This code change will not increase construction costs E-Davidson.doc 2012 ICC FINAL ACTION AGENDA 1217

182 Public Hearing Results Committee Action: Disapproved Committee Reason: The proposed change for a 45 minutes fire resistance rating is an increase without technical justification. Wired glass is typically considered equivalent to a 45 minutes fire protection rating.

Exception: The maximum transmitted temperature rise is not required The area is used only for means of egress and exits directly to the outside. 3. Horizontal exits complying with Section 1025 shall not be required to discharge directly to the exterior of the building. Commenter s Reason: The committee s reason for denial is confusing in that the statement indicates the suggested reference to a 45 minutes fire resistance rating is an increase without justification, then they state that the wired glass equivalent that currently exists is considered equivalent to a 45 minutes of protection. I believe they were referring to the fact that the referenced wired glass equivalent does not have a maximum transmitted temperature rise rating. The suggested modification refers to a fire partition for the method of construction. Though the fire partition requires a one hour rating in accordance with Section 708, the impact is negligible based upon common construction methods and the use of code recognized terms and methods will provide for clarity in design and construction. To address the committee s concern an exception to the maximum transmitted temperature rise has been added. E Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1218

183 E , , Table , ; (IFC [B] , , Table , ) Proposed Change as Submitted Proponent: Dan Casella, Chair, ICC 300 Development Committee, Standard for Bleachers, Folding and Telescopic Seating and Grandstands Revise as follows: (IFC [B] ) Assembly aisle termination. Each end of an aisle shall terminate at cross aisle, foyer, doorway, vomitory or concourse having access to an exit. Exceptions: 1. Dead-end aisles shall not be greater than 20 feet (6096 mm) in length. 2. Dead-end aisles longer than 16 rows 20 feet (6096 mm) are permitted where seats beyond the 16 th row 20-foot (6096 mm) dead-end aisle are no more than 24 seats from another aisle, measured along a row of seats having a minimum clear width of 12 inches (305 mm) plus 0.6 inch (15.2 mm) for each additional seat above seven in the row where seats have backrests or beyond ten where seats are without backrests in the row. 3. For smoke-protected assembly seating, the dead end aisle length of vertical aisles shall not exceed a distance of 21 rows. 4. For smoke-protected assembly seating, a longer dead-end aisle is permitted where seats beyond the 21-row dead-end aisle are not more than 40 seats from another aisle, measured along a row of seats having an aisle accessway with a minimum clear width of 12 inches (305 mm) plus 0.3 inch (7.6 mm) for each additional seat above seven in the row where seats have backrests or beyond ten where seats are without backrests in the row (IFC [B] ) Dual access.

Exception: For smoke-protected assembly seating, the row length limits for a 12-inch-wide (305 mm) aisle accessway, beyond which the aisle accessway minimum clear width shall be increased, are in Table Reason: The intent of this proposal is for coordination with ICC 300 Section 407.3, and This proposal is an extension of the recognition of the fact that bench seating without backrests allows easier and quicker lateral movement along a bleacher type row as compared with rows of seating which are provided with backrests. In seating with backrests, occupants typically must remain facing forward or approximately perpendicular to the aisle access and side step toward the aisle. The wider the aisle access, the more the occupants are allowed to turn and walk toward the aisle. When backrests are not present it is possible to turn and face parallel to the aisle access regardless of aisle access width. This in turn allows a walking style motion instead of side stepping. Seating without backrests also allows easier vertical movements between rows without climbing over seatbacks or using aisles. Although this is not a consideration during normal egress, the benefits to crowd management, security, and emergency medical personnel are obvious. Current IBC aisle access requirements are based on seating with backrests. For the minimum 12 aisle access, 6 seats are allowed between any seat and an aisle. From there that number of seats is increased with increases in aisle access width and smoke protection. This proposal increases the basic number of seats between any seat and an aisle for the minimum 12 aisle access from 6 to 9(single access) or 10(dual access). The increase factors for width and smoke protection remain unchanged. Once the increased number is exceeded in a dual access or single access row, the calculation for the increased access aisle width would start at this point. Example of dual access: Seats with backs 30 seats; = 16; 16 x = 16.8 minimum access aisle width Seats without backs 30 seats; = 7; 7 x = 14.1 minimum access aisle width This proposal also re-introduces the long standing and time tested dead end aisle limit of 16 rows for non-smoke protected seating. The 16 row limit is reasonable considering the attentiveness of people and typically shorter periods of occupancy involved with assembly. It also matches well with the 21 row limit already afforded to smoke protected seating. The purpose of the ICC 300 standard is to establish the minimum requirements to safeguard the public health, safety and general welfare through structural strength, means of egress facilities, stability, and safety to life and property relative to the construction, alteration, repair, operation, and maintenance of new and existing temporary and permanent bench bleachers, folding and telescopic seating, and grandstands.

185 Public Hearing Results Committee Action: Disapproved Committee Reason: There was no technical justification provided for quicker vertical movement claimed in the reason or an increase in the dead end length. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment: Dan Casella, Chair, ICC 300 Development Committee, Standard for Bleachers, Folding and Telescopic Seating and Grandstands; Gene Boecker, AIA, Code Consultants, Inc (CCI); requests Approval as Submitted. Commenter s Reason (Casella): The proposal should be approved as submitted as part of the harmonization efforts between the assembly seating arrangements in IBC and the ICC 300 standard. Quicker vertical movement applies only where seats are without backrests as indicated in the second paragraph of the reason statement. Per IBC , dead-end corridors may be extended from 20 feet to 50 feet under exceptions 1 and feet is approximately equivalent to a maximum of 16 rows of seating. Per IBC 903, sprinklers will typically be required for the A-1 and A-4 nonsmoke-protected applications where assembly aisles are provided. Again, the attentiveness of the people and the shorter period of occupancy allow for an increased dead-end length. In addition, ceilings must be higher to accommodate site lines in assembly seating. This results in larger room volumes for smoke accumulation and affords greater egress time to walk the increased length. When the IBC was assembled from the BOCA, SBC and UBC codes, all three recognized the proposed 16 row dead-end limit for nonsmoker-protected assembly seating. We believe it was merely an oversight that this was not included in the IBC.

Information can be downloaded from the following website: Since its inception in March 2000, the committee has produced 3 editions, the latest edition being All meeting are open to the public. Commenter s Reason (Boecker): The proposal should be approved. The proposal seeks to harmonize the IBC with the ICC 300 standard. The ICC 300 committee had extensive discussions on this issue and agreed that the revision was in keeping with the needs for assembly seating of this type. If this is not approved, there will be a gap between what is allowed in the ICC 300 Standard and what is allowed in the IBC. In a facility such as a high school with fixed seating on one side and a telescoping seating on the other, two different sets of rules would be in place if this is not approved. The history of use demonstrates that this is an appropriate method of seating where no seat backs are provided The purpose of the ICC 300 standard is to establish the minimum requirements to safeguard the public health, safety and general welfare through structural strength, means of egress facilities, stability, and safety to life and property relative to the construction, alteration, repair, operation, and maintenance of new and existing temporary and permanent bench bleachers, folding and telescopic seating, and grandstands.

186 E Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Delete without substitution: Existing buildings. Existing buildings shall comply with Section Reason: This exception is being deleted because it is not needed. Application of the building code for existing buildings begins in chapter 34. The scope of accessibility requirements for existing buildings is specified in chapter 34, specifically in section IBC chapter 11 is not the scoping chapter for existing building accessibility, therefore this exception in chapter 11 is simply redundant and not needed. It is technically an invalid exception because it is a scoping exception for a chapter that does not scope accessibility for existing buildings. Other chapters of the IBC do not have a similar exception because the general scope of the IBC is for new construction with Chapter 34 applicable to scope the IBC or IEBC for existing construction. The general scope of application of the IBC and IEBC to existing buildings is established in IBC Chapter 34; the IEBC as referenced by IBC section as an alternative to IBC chapter 34. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. Cost Impact: None E-BALDASSARRA-CTC.docx Public Hearing Results Committee Action: Disapproved Committee Reason: While the committee agreed with the proponents reason that existing buildings are covered in Chapter 34, the pointer to the existing building requirements in Chapter 34 for accessibility requirements is needed for the more casual user. Coordination with the IEBC may also be necessary depending on other code changes in regards to Chapter 34.

188 E Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Delete without substitution: Day care facilities. Where a day care facility is part of a dwelling unit, only the portion of the structure utilized for the day care facility is required to be accessible. Reason: This exception is invalid within the context of the IBC. A day care facility cannot be part of a dwelling unit because they are two distinct occupancies. If a day care facility and a dwelling unit are in the same building then the building is a mixed occupancy building and the accessibility provisions for each occupancy are applicable, and no exception is required or appropriate. The dwelling unit portion would be a Group R-2 or R-3; the day care facility would be Group I-4, I-2 or E. Accessibility requirements would be scoped to each occupancy group accordingly. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party.

Cost Impact: None E-BALDASSARRA-CTC.docx Public Hearing Results Committee Action: Disapproved Committee Reason: There is value in having this pointer remain since this can be a business in an IRC building. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Carl Baldassarra, Code Technologies Committee, requests Approval as Submitted. Commenter s Reason: Day care facilities should not be singled out as a specific exception for several reasons. Day care conducted in dwelling units is most often found in IRC dwellings rather than IBC dwellings. Also, in efforts to coordinate with the ADAAG by providing a laundry list of exceptions in IBC Section 1103, it is not necessary to specify day care facilities. The ADAAG regulates business use of the home in a wide variety of possible uses, not just day care. Providing this specific exception can be misleading and unnecessary by narrowing the focus of regulated businesses in dwelling units to day care facilities. Where constructed new, any day care occupancy connected to any other occupancy would be considered a mixed use building and should be addressed as such. Therefore, this is literally already covered by Chapter 11. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party.

190 E (New) Proposed Change as Submitted Proponent: David R. Scott, AIA, representing Target Corporation Add new text as follows: Display areas. Display areas that do not exceed 300 square feet (30 m 2 ) in area and are not open to the public are not required to be accessible. Reason: Access to these display areas are not intended by the general public. We feel Section Limited access spaces, do not clearly identify that display areas would fall under this section. We have established a size of 300 sq. ft. to give a limit to a size of a display area as well as to tie into the size established in Section Cost Impact: The code change proposal will not increase the cost of construction (New)-E-Scott.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The phrase display areas is too broad for uniform enforcement. The term display window might be better language for this exception. If this includes any type of employee work area, approach, enter and exit would be required. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: David Scott, AIA, representing Target Corporation, requests Approval as Modified by this Public Comment. Modify the proposal as follows: Display window areas. Display window areas that do not exceed 300 square feet (27.9 sq. meters) in floor area and are less than 7 feet in any plan dimension, and to which the general public is excluded, need not be made accessible. Commenter s Reason: Committee comment indicated that Display areas could be too general or broad. We have revised this to Display Window Areas to help define the scope or area being addressed. Committee also indicated if this includes any type of employee work area, approach, enter and exit would be required. Per section , a space is not considered a room or habitable space unless it is at least 7 ft. in any plan dimension. Additionally, section for work areas limit accessible requirement to 300 sq. ft. Therefore, a display window area that is less than 7 ft. in any plan dimension would not be considered a room or habitable space. The new language being proposed is to add clarity. If an area is considered too small to be considered a room or habitable space, it would also not be required to be accessible. This proposed change will help tie section together with section 1208 and add clarity and consistency in the language. E Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1226

191 E , Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: Required. Where parking is provided, accessible parking spaces shall be provided in compliance with Table , except and as required by Sections through Where more than one parking facility is provided on a site, the number of parking spaces required to be accessible shall be calculated separately for each parking facility Groups I-1, R-1, R-2 and R-4 R-2 and R-3. In addition to the parking required by Table , in Groups I-1, R-1, R-2 and R-4, where parking is provided for Accessible and Type A units, at least one accessible parking space shall be provided for each unit. At least 2 percent, but not less than one, of each type of parking space provided for occupancies in Groups R-2 and R-3, which are required to have Accessible, Type A or Type B dwelling or sleeping units, shall be accessible. Where parking is provided within or beneath a building, accessible parking spaces shall also be provided within or beneath the building Hospital outpatient facilities. At least 10 percent, but not less than one, of care recipient and visitor parking spaces provided to serve hospital outpatient facilities shall be accessible Rehabilitation facilities and outpatient physical therapy facilities. At least 20 percent, but not less than one, of the portion of care recipient and visitor parking spaces serving rehabilitation facilities specializing in treating conditions that affect mobility and outpatient physical therapy facilities shall be accessible. Reason: The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. When parking is provided for residents, this proposal would require an accessible space for each Accessible and Type A unit, as well as accessible parking for the remainder of the units. This should meet both ADA and FHA. Literally, current IBC is asking for 2% of the parking provided for the three types of accessible units ADA requires 2% of parking for all units that are not Accessible or Type A only when there is more than one parking space per unit. Table already gets you more than 2%. (2010 ADA ) Since Accessible units also required in Group I-1 assisted living, and these facilities may provide parking for residents, this Group has been added to the list. If the assisted living facility does not provide parking spaces for residents, the parking lots would just meet the general parking lot requirements. Section and are relevant to only portions of the parking facilities for hospitals and rehabilitation facilities. Areas such as employee parking should use Table for the number of accessible spaces. Cost Impact: None #2-E-BALDASSARRA-CTC.docx Public Hearing Results Committee Action: Disapproved Committee Reason: The proponent requested disapproval so that they can work with the National Association of Home Builders to address parking for Type B units and single family and townhouse complexes with no accessible units.

192 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Carl Baldassarra, Code Technologies Committee, requests Approval as Modified by this Public Comment. Modify the proposal as follows: Required. Where parking is provided, accessible parking spaces shall be provided in compliance with Table , except and as required by Sections through Where more than one parking facility is provided on a site, the number of parking spaces required to be accessible shall be calculated separately for each parking facility Groups I-1, R-1, R-2, R-3 and R-4. Accessible parking spaces shall be provided in Groups I-1, R-1, R-2, R-3 and R-4 occupancies in accordance with items 1 through 4 as applicable. 1. In Groups R-2, R-3, and R4 occupancies which are required to have Accessible, Type A or Type B dwelling or sleeping units, at least 2 percent, but not less than one, of each type of parking space provided shall be accessible. 2. In Groups I-1 and R-1 occupancies accessible parking shall be provided in accordance with Table In addition Where at least one parking space is provided for each dwelling unit or sleeping unit, to the parking required by Table , in Groups I-1, R-1, R-2 and R-4, where parking is provided for Accessible and Type A units, at least one accessible parking space shall be provided for each Accessible and Type A unit. 4. Where parking is provided within or beneath a building, accessible parking spaces shall also be provided within or beneath the building. Commenter s Reason: The intent of this public comment is to clarify and coordinate parking requirements for what may be considered residential occupancies under Fair Housing and ADA. The additional language in the base paragraph is to editorial to clarify requirements. Item 1 - The proposed comment reintroduces the basic requirement that for Group R-2 and R-3 (and R-4 per Section 310.6) when parking is made available at least 2%, but no less than one, space must meet the accessible requirements. See also E for signage requirements. These spaces are not required to be signed as accessible providing the space is provided. Item 2 This is added as coordination with item 3. If this section will include where Accessible units are required, then accessible parking for R-1 and I-1 must be clear. Item 3 - This comment also address the change in the ADA which requires a one-to-one ratio when parking is provided for each dwelling unit, an accessible parking space is required for each dwelling unit that is an Accessible or Type A dwelling Unit. Item 4 This is existing text.

193 E , Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: Group I-1. Accessible units and Type B units shall be provided in Group I-1 occupancies in accordance with Sections and Accessible units. In Group I-1, other than assisted living facilities, at least 4 percent, but not less than one, of the dwelling units and sleeping units shall be Accessible units. In Group I-1 assisted living facilities, at least 10 percent, but not less than one, of the dwelling units and sleeping units shall be Accessible units Type B units. In structures with four or more dwelling units or sleeping units intended to be occupied as a residence, every dwelling unit and sleeping unit intended to be occupied as a residence shall be a Type B unit. Exception: The number of Type B units is permitted to be reduced in accordance with Section Group R-4. Accessible units and Type B units shall be provided in Group R-4 occupancies in accordance with Sections and Accessible units. In Group R-4, other than assisted living facilities, at least one of the dwelling or sleeping units shall be an Accessible unit. In Group R-4 assisted living facilities, at least two of the dwelling or sleeping units shall be an Accessible unit Type B units. In structures with four or more dwelling units or sleeping units intended to be occupied as a residence, every dwelling unit and sleeping unit intended to be occupied as a residence shall be a Type B unit. Exception: The number of Type B units is permitted to be reduced in accordance with Section Reason: The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. The intent of this code change is to establish a minimum number of Accessible units required in Assisted Living Facilities for Group I-1 and R-4. The 10% Accessible units is based on anticipated need in these types of facilities. The curre nt ADA requirements address residential facilities and long term care facilities, typically hospitals and nursing homes. The text does not directly address what the International Codes refer to as Assisted Living or Group I-1 facilities. The current text requires the following: 100% Accessible units in Group I-2 rehabilitation facilities; 50% Accessible units in Group I-2 nursing homes; 4% Accessible units in all Group I-1 and 2% Type A units in Group R-2 apartment buildings. The 2009 IBC had 10% Accessible units for residential board and care facilities, but the deletion of that term in the 2012 IBC resulted in the loss of that requirement. This addition will establish a minimum level for Group I-1 assisted living facilities while leaving other Group I-1 facilities to remain at 4%. Facilities can always choose to exceed this limit depending on the needs of their clientele and the desire of the facility to have optimum flexibility. Since these facilities are custodial care, and not nursing care, 10% Accessible units should meet demand. The committee feels that if the building code addresses the minimum accessibility needs for these types of facilities, then the federal government may not feel that they need to establish additional accessibility requirements. Cost Impact: Increase E-BALDASSARRA 2012 ICC FINAL ACTION AGENDA 1229

194 Public Hearing Results Committee Action: Approved as Submitted Committee Reason: This proposal fills a gap between apartment living and nursing homes. The 10% is based on the anticipated need in assisted living facilities. This provision was lost when the definition for residential care facilities was removed during the last cycle. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Carl Baldassarra, Code Technologies Committee, requests Approval as Modified by this Public Comment. Modify the proposal as follows: Accessible units. In Group I-1, other than assisted living facilities Condition 1, at least 4 percent, but not less than one, of the dwelling units and sleeping units shall be Accessible units. In Group I-1 assisted living facilities Condition 2, at least 10 percent, but not less than one, of the dwelling units and sleeping units shall be Accessible units Accessible units. In Group R-4, other than assisted living facilities Condition 1,at least one of the dwelling or sleeping units shall be an Accessible unit. In Group R-4 assisted living facilities Condition 2, at least two of the dwelling or sleeping units shall be an Accessible unit. Commenter s Reason: Code change E186 is a technical change which proposes to increase the required number of Accessible sleeping unit for assisted living arrangements where the anticipated need is greater than the current 4%. For Group I-1, Condition 2, this proposal will be consistent with anticipated need within these types of facilities. This proposal was approved by the committee in Dallas. The purpose of this public comment is limited to the editorial coordination of terminology with the approval of Code change G At the Code Development Hearing, the IBC - General committee approved as submitted G31-12 which created two occupancy conditions for Group I-1, similar to what is currently in the IBC for Group I-3 and was approved for Group I-2 in G257. The end result is that where warranted, the code would call out Group I-1 into Condition 1, where residents can evacuate without assistance, and Group I-1, Condition 2, where residents may need limited assistance in evacuation. As indicated in the reason statement for G31, the benefit of the condition concept, when compared to creating new use groups, (i.e. Group I-5 or I-6) is that a majority of code requirements would still apply to all Group I-1 occupancies. Following the successful action on G31, the Care Study Group for the Code Technologies Committee (CTC) did a a review of code changes submitted in the 2012 Cycle which are unique to Group I-1 to determine whether or not the condition designation was necessary in order to distinguish between the two Group I-1 conditions. Code change E186 is one such application where the Group I-1, Condition 1 and Group I-1, Condition 2 designation is warranted, and therefore this public comment is being submitted by the CTC. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as Areas of Study. The Area of Study for this code change and public comment is called Care Facilities.

The intent is to try and address the new style of dormitory facilities that operate like dorms, but look like apartments. There has also been the interpretation that fraternities and sororities are a single dwelling unit for purposes of accessibility. The statement about congregate residences should help address how to count units for these types of facilities. This should be extended to the 16 or fewer congregate residences permitted in Group R-3 and R-4. Group R-4 facilities are group homes and therefore are always congregate residences; therefore they will not include dwelling units. Below is an example of student on-campus housing at Indiana University. While it looks like an apartment, it is handled administratively by the university exactly the same as typical dorm room assignments.

197 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Carl Baldassarra, Code Technologies Committee, requests Approval as Modified by this Public Comment. Modify the proposal as follows: Type A units. In Group R-2 occupancies containing more than 20 dwelling units or sleeping units, at least 2 percent but not less than one of the units shall be a Type A unit. All Group R-2 units on a site shall be considered to determine the total number of units and the required number of Type A units. Type A units shall be dispersed among the various classes of units. Bedrooms within monasteries and convents shall be counted as sleeping units for the purpose of determining the number of units. Where the sleeping units are grouped into suites, only one sleeping unit in each suite shall be permitted to count towards the number of required Type A units. Exceptions: 1. The number of Type A units is permitted to be reduced in accordance with Section Existing structures on a site shall not contribute to the total number of units on a site Type B units. Where there are four or more dwelling units or sleeping units intended to be occupied as a residence in a single structure, every dwelling unit and sleeping unit intended to be occupied as a residence shall be a Type B unit. Exception: The number of Type B units is permitted to be reduced in accordance with Section Group R-2 other than apartment houses, monasteries and convents. In Group R-2 occupancies, other than apartment houses, monasteries and convents, Accessible units and Type B units shall be provided in accordance with Sections and Bedrooms within congregate living facilities shall be counted as sleeping units for the purpose of determining the number of units. Where the sleeping units are grouped into suites, only one sleeping unit in each suite shall be permitted to count towards the number of required Accessible units. (Portions of proposal not shown remain unchanged.) Commenter s Reason: The new style of dorm setups are looking like dwelling units but still operate as dormitories. In large facilities, the Accessible rooms should not be all grouped into one suite, so that the students have options. In congregate living arrangements in Group R-3 and R-4, with the maximum size at 16 occupants, this is not an issue, therefore further modification of these sections is not needed. This proposal is consistent with the intent in the DOJ Regulations for housing for education in the adoption of the 2010 ADA Standards for Accessible Design.

198 E Proposed Change as Submitted Proponent: Cheryl Kent, U.S. Department of Housing and Urban Development Revise as follows: Multistory units. A multistory dwelling or sleeping unit which is not provided with elevator service is not required to be a Type B unit. Where a multistory unit is provided with external elevator service to only one floor, the floor provided with elevator service shall be the primary entry to the unit, shall comply with the requirements for a Type B unit and a kitchen and toilet facility shall be provided on that floor. Reason: At the time that HUD s Fair Housing Accessibility Guidelines were drafted, HUD included provisions for multistory units when such units may be located in a building with a public elevator, requiring that the story that is served by the building elevator be the primary entry to the unit, that this story comply with the accessibility requirements of the Fair Housing Act with respect to the rooms located on the entry/accessible floor, and that this floor include a complying bathroom or powder room. It was HUD s expectation that the main living areas, including the kitchen, living and dining rooms would be on this story/floor, but that this story may not always include an accessible bathroom or powder room, so the Guidelines specifically stated that it would. Since that time, there have been new building types introduced into the housing market, including a few situations where multistory units, located in a building with a public elevator, did not have the kitchen located on the story with the primary entry; or there were multiple floors, rather than the typical, 2-story unit with kitchen, living and dining on the main entry level and bedrooms and bathrooms above. As the Fair Housing Act requires usable kitchens and bathrooms, it has been our position that the kitchen also needs to be on the primary entry level of such multistory units. This code change proposal is intended to incorporate this requirement. Cost Impact: There should be no significant cost impact because the typical building situation in which a multistory unit may be located in a building with public elevator service most often already does include the primary living areas and the kitchen on the primary entry level. In those few situations where this may not be the case, this changed code language will make it clear, from the outset, before design and construction, that the story of the unit that is served by the building elevator will be the primary entry to the unit, will have rooms on this level that comply with the accessibility requirements, including an accessible kitchen and bathroom or powder room; thus assuring that costs, if any, will be minimal E-Kent.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The proposed language could be read to require bathrooms and kitchens within a sleeping unit. Adding the words where provided within the unit would address the concern. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment 1: Cheryl Kent, representing U.S. Department of Housing and Urban Development, requests Approval as Modified by this Public Comment. Modify the proposal as follows: Multistory units. A multistory dwelling or sleeping unit which is not provided with elevator service is not required to be a Type B unit. Where a multistory unit is provided with external elevator service to only one floor, the floor provided with elevator service shall be the primary entry to the unit, shall comply with the requirements for a Type B unit and, where provided within the unit, a living area, a kitchen and a toilet facility shall be provided on that floor ICC FINAL ACTION AGENDA 1234

199 Commenter s Reason: The Committee indicated that the language as originally written was unclear as to whether HUD wanted the kitchen to be accessible (even if located on the upper story of the multistory unit, or whether HUD wanted to ensure that the kitchen was located on the accessible level. The Committee also expressed concern that some types of dwelling units may not have a kitchen within the unit. The changes above are intended to address the Committee s concerns and also further clarify HUD s interpretation of the language in HUD s Fair Housing Accessibility Guidelines, which this provision in the code is intended to reflect. As HUD explained in its reason statement for this proposed change, at the time that HUD s Fair Housing Accessibility Guidelines (the Guidelines) were drafted, HUD included provisions for multistory units when such units may be located in a building with a public elevator, requiring that the story that is served by the building elevator be the primary entry to the unit, that this story comply with the accessibility requirements of the Fair Housing Act with respect to the rooms located on the entry/accessible floor, and that this floor include a complying bathroom or powder room. It was HUD s expectation that the primary entry level of the dwelling unit would include those living areas typically found on the lower story of a multistory unit and would include the kitchen and the living area, but may not include a powder room or bathroom. For this reason, the Guidelines specified a powder room or bathroom would be included on the primary entry level. (See attached graphic). It has since come to HUD s attention that some multistory dwelling units are being built with only the primary entry to the unit and a bathroom or powder room on the story served by the building elevator, with no other rooms or spaces on this level that would comply with the requirements for a Type B unit. This is not what HUD intended and it is not how HUD interprets the language in the Guidelines. HUD is proposing the above modification to address the concerns of the Committee and to also make clear that the primary entry level must include the living area, as well as the kitchen and a toilet facility, with the understanding that this is when these facilities are provided within the dwelling unit. Once again, HUD wishes to emphasize that this proposed change applies only to multistory dwelling units or sleeping units that are located in a building with a public elevator, and not multistory units located in buildings without a public elevator (e.g. townhouses). While most multistory dwelling units that are located in a building with a public elevator will be likely to have a living area, a kitchen and a toilet facility within the unit, the language as modified makes it clear that when those facilities are, in fact, provided within the unit, they must be on the accessible/primary entry level. We believe the language as modified addresses the Committee s concerns. Public Comment 2: Gene Boecker, AIA, Code Consultants, Inc. (CCI), requests Approval as Modified by this Public Comment. Modify the proposal as follows: Multistory units. A multistory dwelling or sleeping unit which is not provided with elevator service is not required to be a Type B unit. Where a multistory unit is provided with external elevator service to only one floor, the floor provided with elevator service shall be the primary entry to the unit, shall comply with the requirements for a Type B unit and, where provided within the unit, a kitchen and toilet facility shall be provided on that floor. Commenter s Reason: The committee felt that the language as originally written could be misinterpreted and offered this suggestion to resolve the concern. This makes it clear that the intent is to locate the kitchen on the accessible level in multi-story units; but, only where there is a kitchen in the unit. The logical also applies to the toilet room ICC FINAL ACTION AGENDA 1235

200 Although it is unlikely that these elements would not be located within the unit, this addresses the concern and removes the objections to its approval. E Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1236

201 E Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: Lavatories. Where lavatories are provided, at least 5 percent, but not less than one, shall be accessible. Where an accessible lavatory is located within the accessible water closet compartment that lavatory shall not be the only accessible lavatory in the multi-compartment toilet room. Where the total lavatories provided in a toilet room or bathing facility is six or more, at least one lavatory with enhanced reach ranges shall be provided. Reason: Accessible lavatories must be available to all users of the toilet room any time the room is open. If the only accessible lavatory is within the accessible stall, others in the bathroom would not have access to that lavatory within the stall when the stall was in use. To prevent this, an additional accessible lavatory within the room should still be available for all users. It is not the intent of this section to prohibit someone from providing an accessible lavatory within an accessible stall, only that it not be the only one.

Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Gene Boecker, AIA, Code Consultants, Inc (CCI), requests Approval as Modified by this Public Comment. Modify the proposal as follows: Lavatories. Where lavatories are provided, at least 5 percent, but not less than one, shall be accessible. Where an accessible lavatory is located within the accessible water closet compartment that at least one additional accessible lavatory shall not be provided the only accessible lavatory in the multi-compartment toilet room outside the water closet compartment. Where the total lavatories provided in a toilet room or bathing facility is six or more, at least one lavatory with enhanced reach ranges shall be provided. Commenter s Reason: The proposed language does not change the intent of the section. It rephrases the text into a requirement instead of something to avoid. As originally written, it is conceivable that a second accessible lavatory in a second accessible water closet compartment would meet the requirement. That is not the original intent and not in keeping with the intent to harmonize the 2012 ICC FINAL ACTION AGENDA 1237

202 text with the ADA. The proposed language is specific in the manner in which the second lavatory must be provided and consistent with Section of the 2010 ADA Standards for Accessible Design. E Final Action: AS AM AMPC D 2012 ICC FINAL ACTION AGENDA 1238

203 E (New), E105.4 Proposed Change as Submitted Proponent: Cheryl Kent, U.S. Department of Housing and Urban Development Add a new section: Mail receptacles. Where provided, mail receptacles shall be accessible in accordance with Sections or Dwelling units and sleeping units. Where mail receptacles are provided for Accessible, Type A or Type B dwelling and sleeping units, accessible mail receptacles shall be provided in accordance with or Centralized mail receptacles. Where each individual mail compartment of a centralized mail receptacle is assigned to a specific dwelling unit or sleeping unit, the individual mail compartments shall comply with or Buildings without an elevator. In a structure without an elevator, all individual mail compartments assigned to Accessible Units, Type A Units and Type B Units in each location shall be accessible Buildings with an elevator. In a structure with an elevator, fifty percent of all individual mail compartments in each location shall be accessible. Individual mail compartments assigned to Accessible and Type A units shall be included in the accessible mailboxes. In addition to the individual mail compartments assigned to dwelling or sleeping units, an additional number of individual mail compartments that is equal to ten percent of the total number of dwelling units and sleeping units, but not less than one, at each location shall be accessible Parcel lockers. All parcel lockers of centralized mail receptacles shall be accessible Individual house-mounted and curbside mail receptacles. Where an individual housemounted or curbside mail receptacle serves a dwelling unit or sleeping unit that is required to be an Accessible unit, Type A unit or Type B unit, the mail receptacle shall be accessible Other occupancies. Where mail receptacles are provided in occupancies not falling within the purview of Section , at least 5 percent, but not less than one, of each type in each location, shall be accessible. (Renumber subsequent sections) Delete without substitution: E105.4 Mailboxes. Where mailboxes are provided in an interior location, at least 5 percent, but not less than one, of each type shall comply with ICC A In residential and institutional facilities, where mailboxes are provided for each dwelling unit or sleeping unit, mailboxes complying with ICC A117.1 shall be provided for each unit required to be an Accessible unit. Reason: This proposed change is intended to specifically address accessibility requirements for mailboxes that are provided for buildings that are covered by the Fair Housing Act s (FHAct) accessible design and construction requirements and HUD s Fair Housing Accessibility Guidelines (HUD s Guidelines). Under the IBC, dwelling units and sleeping units that are covered by the FHAct and HUD s Guidelines are known as Type B Dwelling Units, so the focus of the proposal is on Type B Units; at the same time however, this proposal also will easily include Accessible Units and Type A units ICC FINAL ACTION AGENDA 1239

204 As background, it came to HUD s attention that Section E105.4 is being interpreted as applying to mailboxes serving Type B dwelling units. This was not HUD s understanding of the IBC, rather, we understood that Section covered mailboxes as well as all other types of public and common use facilities serving Type B dwelling units, and that absent specific scoping requirements to scope less than 100% of individual mailboxes, that all mailboxes were required to be accessible consistent with HUD s position in its Guidelines, which also does not scope less than 100% of mailboxes serving covered dwelling units. The above language will resolve this misunderstanding by striking the language in Appendix E and adding the new language outlined above. HUD is also aware that HUD s position on mailboxes provided at FHAct covered buildings and current U.S. Postal Service regulations are not in harmony. HUD and U.S.P.S. held a number of discussions and meetings but are not in agreement on a resolution. Nevertheless, HUD recognizes that a 100% scoping requirement for mailboxes in hi-rise elevator buildings, coupled with situations where wall space may be limited, poses challenges for designers and builders in meeting the FHAct requirements as well as those in the IBC and ICC A117.1 for accessible reach ranges. Therefore, we recognize in this proposal that up to 50% of Type A or B units in a building with one or more elevators may not be served by an accessible mailbox. For this reason, this proposal relies on the provision of an additional number of unassigned mailboxes within the accessible reach range to be available, at the time of first occupancy, to serve persons with disabilities who may reside in these units and who may need an accessible mailbox. Through this code change proposal, we are proposing a resolution that supports our on-going desire to promote consistency between the accessibility requirements in the FHAct and the IBC. In addition, HUD believes this proposal will resolve the conflict in a manner that is consistent with HUD s efforts to move toward more widely accepted accessible reach ranges that are in the more recent editions of the ICC A117.1 standard, as well as in recent government standards for the ADA. In this regard, although HUD s Guidelines use the 1986 edition of ICC A117.1, our proposal is in keeping with several of the more recent editions of IBC and ICC A117.1 that HUD has recognized as safe harbors for compliance under the FHAct, and which use the 48-inch maximum reach range for the high reach. Consequently, we are not recommending changes to the ICC A117.1 as part of this proposal, nor do we intend to do so. We would like to ensure that architects and builders involved in designing and constructing buildings that are covered by the Fair Housing Act provide for accessibility of mailboxes consistent with HUD s regulations and Guidelines. Developers who deviate from these standards by providing mailboxes at higher reach ranges have been subject to enforcement proceedings brought by HUD as well as litigation brought by the Department of Justice. The Department of Justice has entered into a number of consent decrees which have required the developer to change the height of mailboxes serving covered multifamily dwellings. We believe this change is needed to ensure that the IBC is consistent with the Fair Housing Act and HUD s regulations and Guidelines, and to avoid unnecessary litigation with respect to mailboxes serving Type B dwelling units. Cost Impact: There should be no significant cost impact since the IBC currently contains text at Section that would apply to mailboxes, like any other public and common use area, and again, absent scoping requirements, should have already been requiring 100% accessibility of mailboxes serving Type B dwelling units. However, by adding this new text to address mailboxes specifically, rather than just generally in Section , the IBC will be assuring consistency with the Fair Housing Act, HUD s regulations and the Guidelines E-Kent.doc Public Hearing Results Committee Action: Approved as Submitted Committee Reason: This proposal provides guidance for mailboxes, which are already shared and common spaces for housing covered by Section This proposal will address concerns and issued brought up by representatives from Housing and Urban Development and the U.S. Postal Service during the last cycle s hearings. 50% of the mailboxes within the range will allow for a reasonable number of mailboxes within a facility to be accessible. Asking for 100% can be too restrictive in for large complexes or dormitory facilities. The extra 5% would allow for mailboxes to be pre-assigned or not, depending on what the facility wishes. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because public comments were submitted. Public Comment 1: Thomas Meyers, Colorado Code Consulting, LLC., representing self, requests Approval as Modified by this Public Comment. Modify the proposal as follows: Buildings with an elevator. In a structure with an elevator, fifty percent of all individual mail compartments in each location shall be accessible. Individual mail compartments assigned to Accessible and Type A units shall be included in the accessible mailboxes. In addition to the individual mail compartments assigned to dwelling or sleeping units, an additional number 2012 ICC FINAL ACTION AGENDA 1240

205 of individual mail compartments that is equal to ten percent of the total number of dwelling units and sleeping units, but not less than one, at each location shall be accessible. (Portions of proposal not shown remain unchanged.) Commenter s Reason: This proposal was approved on the merits of providing needed guidance on the number of mailboxes that are deemed accessible. The 50% requirement seems quite conservative. One rarely finds users confined to needing the accessible wheelchair derived reach ranges in most circumstances, including senior or low income residential projects. The occasional need for an accessible (within reach range) mailbox will be fairly rare and certainly be accommodated within the 50% provided. The added 10% in addition to the 50% is extremely restrictive If the intent is to always have one available just in case a reasonable accommodation is requested, only one spare compartment is really necessary. Considering normal vacancy rates, it is very likely that among the 50% accessible, at least one box may be instantly available. If not, mailboxes can be easily switched among tenants to accommodate the need. It should also be noted that the construction of such a large quantity of unused boxes is wasteful and unprecedented in the code. As a minimum standard document, the building code should not require capital investment and ongoing maintenance expenses to possibly accommodate a very unlikely eventuality. Public Comment 2: Steven Orlowski, representing National Association of Home Builders (NAHB), requests Disapproval. Commenter s Reason: The original proposal submitted by HUD far exceeds the requirements by establishing a fifty percent requirement on buildings serviced by an elevator for all mailboxes to be within the acceptable reach ranges and adds requirements for parcel lockers which are not mentioned anywhere in the Fair Housing or ADA. The fifty percent requirement in the proposal will create conflicts between the IBC and the United States Postal Services standard 4B, which regulates both the height and width of wall-mounted centralized mail receptacles. Where there are a large number of mail receptacles servicing a multistory residential dwellings, there may not be enough wall space to accommodate fifty percent of the receptacles to be mounted between the 15 minimum and 48 maximum reach ranges. These requirements conflict with the minimum and maximum heights for centralized mailboxes under the USPS Standard 4b and NAHB urges the FAH assembly to disapprove this proposal.

206 E Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Delete without substitution: Operable window. Where operable windows are provided in rooms that are required to be accessible in accordance with Sections , , , , , , and , at least one window in each room shall be accessible and each required operable window shall be accessible. Reason: This list is a reference for Accessible units and Type A units. Windows within dwelling units and sleeping units are addressed in ICC A117.1, therefore they are not needed here. The ADA/ABA has some requirements for operable windows, but has a series of exceptions, including one for residential uses. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. Cost Impact: None E-BALDASSARRA-CTC.docx Public Hearing Results Committee Action: Disapproved Committee Reason: The proponent asked for disapproval in order to address scoping issues/differences between transient and non-transient lodging found in the 2010 ADA Standard for Accessible Design. Assembly Action: None Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Carl Baldassarra, Code Technologies Committee, requests Approval as Submitted. Commenter s Reason: The MOE committee disapproved this change because the CTC representative asked for some additional time to investigate some possible conflicts with ADA. The concern was over operable windows in Accessible units in transient lodging. Since there are window requirement in Accessible Units (ICC A ) it would be appropriate to address the technical requirements at that location. Therefore, in our opinion there is no scoping conflict with ADA by removing this section from the IBC. A change proposal has been submitted to the ICC A117.1 to deal with the technical criteria for windows within Accessible or Type A dwelling units. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as Areas of Study. The Area of Study for this code change and public comment is called IBC Coordination with the new ADAAG.

208 E , 1110 (New) Proposed Change as Submitted Proponent: Carl Baldassarra, P.E., FSFPE, Chair, ICC Code Technology Committee Revise as follows: SECTION 1110 RECREATIONAL FACILITIES Recreational and sports facilities exceptions. Recreational and sports facilities shall be required to be accessible shall be exempt from this chapter to and shall be on an accessible route to the extent specified in this section Play Areas. Play areas containing play components designed and constructed for children shall be accessible and be located on an accessible route. Reason: This proposal is part of a coordination effort with the 2010 ADA Standard for Accessible Design and the new technical provisions for recreational facilities found in 2009 ICC A117.1 Chapter 11. This overall proposal for recreational facilities has been divided into parts so that the membership can look at each type of recreational facilities on its own merit. The overall intent is to provide access to recreational facilities so that persons with mobility impairments can participate to the best of their ability. The requirements are not intended to change any essential aspects of that recreational activity. This proposal contains scoping provisions for play areas. Currently, Section addresses structures intended as children s playgrounds and Section exempts swings and other playground equipment accessory to detached one- and twofamily dwellings from permits. To the extent that children s play facilities are covered by the IBC, they should be accessible to children with disabilities. These scoping requirements are reasonable and are the result of recommendations from a regulatory negotiation committee the Access Board established for this purpose that included ASTM Public Playground, Soft Contained Play, and Playground Surfacing Systems Committees manufacturers of play equipment, landscape architects, government associations, elementary school associations, and organizations representing people with disabilities. Since the Access Board s guidelines were published in late 2000, manufacturers offer play equipment complying with these scoping and technical criteria. The 2009 edition of the ICC A117.1, Section 1108, contains technical criteria for play areas consistent with the 2010 ADA Standard. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as areas of study. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website: Since its inception in April, 2005, the CTC has held twenty-two meetings all open to the public. Cost Impact: None This will be required by the 2010 ADA Standard for Accessible Design. 1110#4-E-BALDASSARRA-CTC.doc Public Hearing Results Committee Action: Disapproved Committee Reason: The committee disapproved this change due to concerns over how technically playground equipment could be made accessible and that it may be very difficult to achieve. While some residential facilities may not have to comply with ADA requirements for access into or onto playground equipment, there were questions on if an accessible route would be required to the playground as a common use space for residents. Assembly Action: None 2012 ICC FINAL ACTION AGENDA 1244

209 Individual Consideration Agenda This item is on the agenda for individual consideration because a public comment was submitted. Public Comment: Carl Baldassarra, Code Technologies Committee; Gene Boecker, AIA, Code Consultants, Inc (CCI); requests Approval as Submitted. Commenter s Reason (Baldassarra): The MOE committee disapproved this change because of testimony from NAHB and the National Apartment Association that pools and playgrounds connected with residential facilities are not required to comply with the 2010 ADA Standard for Accessible Design; therefore, asking them to comply with ICC A117.1 for playgrounds would be exceeding ADA requirements. The MOE committee also stated that they were not sure how someone could make a playground accessible. These provisions are already in the ICC A117.1, Section These requirements were developed originally by the Access Board and included many representatives from the playground equipment industry. The ICC Board established the ICC Code Technology Committee (CTC) as the venue to discuss contemporary code issues in a committee setting which provides the necessary time and flexibility to allow for full participation and input by any interested party. The code issues are assigned to the CTC by the ICC Board as Areas of Study. The Area of Study for this code change and public comment is called IBC Coordination with the new ADAAG. Information on the CTC, including: meeting agendas; minutes; reports; resource documents; presentations; and all other materials developed in conjunction with the CTC effort can be downloaded from the following website Since its inception in April, 2005, the CTC has held twenty-four meetings all open to the public. In addition to holding face-to-face meetings, the CTC established Study Groups where any interested party can participate in conference calls on specific subjects such as this area of study without having to attend the face-to-face meetings. The requirements for playgrounds are basically are as follows. Play components are elements designed to offer opportunities to play, socialize or learn. They can be stand alone or part of a composite play structure. Swings, spring riders, water tables, playhouses, slides and climbers are just a few examples of play components. Ground-level play components are accessed from the ground, such as swings, spring riders or panels. Elevated play components are part of a composite structure accessed from a platform or deck, such as slides or climbers. All accessible play components must be integrated so there is not a separate accessible area. At least one of each type of play component available at ground level must be on an accessible route. Additional ground-level play components may be required depending on the number of elevated play components provided. This two-part evaluation is designed to provide a variety of experiences for individuals who choose to remain with their mobility device and not transfer to elevated components. If ramps provided access to at least 50 percent of the elevated play components, which also include three different types, then additional ground level play components are not required. At least 50 percent of elevated play components must be accessed by ramps or transfer systems. Where elevated play areas have more than 20 components, at least 25 percent of the elevated play components must be accessed by a ramp. Where elevated play areas have 20 or fewer components, all the routes can be transfer systems (ICC A ) The surfaces around the play areas must consider wheelchair access as well as child fall safety issues. The smaller size of children and how they move around the space is also considered in the requirements. Ground-accessible routes are required to be at least 60 inches wide (to allow wheelchairs to pass) and with a maximum slope of 1:16. There are exceptions to deal with access around elements and transitions at changes in materials. Where ramps are used for access to elevated play components, the maximum rise per ramp run is 12 inches, and handrails are at a height of 20 inches to 28 inches. A transfer platform is a series of steps allowing access to the elevated play areas. The first platform is between 11 and 18 inches above the ground and unobstructed on the transfer side. A series of platforms can then be used to move up into the structure, each with a maximum rise of 8 inches. The size of each platform/step is a minimum of 24 wide and at least 14 inches deep. Some type of support for stability must be provided, but options are left open (ICC A ). Play tables, including water or sand tables, should provide knee clearances of 24 inches high and with the table top or edge (i.e., at sand or water tables) not more than 31 inches high (ICC A ). Depending on the age of the children the play component is designed for, a better design would provide a lower reach range than required. Based on research from the U.S. Access Board, the recommended heights are 20 to 36 inches for 3- to 4-year-olds, 18 to 40 inches for 5- to 8-year-olds and 16 to 44 inches for 9- to 12-year- olds. Soft, contained- play equipment allow individuals to enter a fully enclosed play environment that uses pliable materials such as plastic, soft padding and fabric. When three or fewer entry points are provided, at least one must be on an accessible route. When four or more entry points are provided, at least two must be on an accessible route (ICC A ) Following are examples of accessible playground elements ICC FINAL ACTION AGENDA 1245

210 Commenter s Reason (Boecker): The committee discussed whether play features could be made accessible. They are and they have been for some time now. The specific means to do so is identified in the 2009 ICC/ANSI A117.1 and the 2010 ADA Standards for Accessible Design. By the time the 2015 IBC is adopted, this issue will have been settled much more clearly than it is now because the 2010 Standards will have been in effect for a half dozen years. Regarding the question of scoping in residential areas, the ICC should make it clear that, as an organization, it supports accessibility and would vote to have accessibility for play areas associated with residential occupancies just as much as nonresidential occupancies. If the organization intends to demonstrate its desire for leadership in accessibility, then the scoping should include all occupancies and not be limited to that within the ADA. There are other areas in the code were the IBC requires accessibility and the ADA does not (e.g. churches). Access to play areas and play components is appropriate for all occupancies.
